165-526: Kinescope / ˈ k ɪ n ɪ s k oʊ p / , shortened to kine / ˈ k ɪ n iː / , also known as telerecording in Britain, is a recording of a television program on motion picture film directly through a lens focused on the screen of a video monitor . The process was pioneered during the 1940s for the preservation, re-broadcasting, and sale of television programs before the introduction of quadruplex videotape , which from 1956 eventually superseded
330-828: A fair trial . The English monarchs, through inheritance of substantial territories in France and claims to the French crown, were also heavily involved in conflicts in France, most notably the Hundred Years' War , while the Kings of Scots were in an alliance with the French during this period. Early modern Britain saw religious conflict resulting from the Reformation and the introduction of Protestant state churches in each country. The English Reformation ushered in political, constitutional, social and cultural change in
495-451: A nitrate film base , which is highly flammable. Nitrate film fires were virtually impossible to extinguish. A significant number of fatal accidents occurred in theatrical projection booths, where the heat of the projector lamp made ignition a possibility. Amateur filmmaking ( home movies ) slowly developed during this period. Kodak developed a heat-resistant 'safety base' for home projection. In 1909, tests showed cellulose diacetate to be

The prevailing wind is from the southwest and bears frequent spells of mild and wet weather from the Atlantic Ocean, although the eastern parts are mostly sheltered from this wind. Since the majority of the rain falls over the western regions,
825-604: A welfare state was established, and a comprehensive, publicly funded healthcare system, the National Health Service , was created. The rise of nationalism in the colonies coincided with Britain's much-diminished economic position, so that a policy of decolonisation was unavoidable. Independence was granted to India and Pakistan in 1947. Over the next three decades, most colonies of the British Empire gained their independence, and many became members of
990-444: A "normal" print or a deluxe print (on more-costly print film like Kodak Vision Premiere) with slightly greater saturation and contrast. Use of film remained the dominant form of cinematography until the early 21st century when digital formats supplanted the use of film in many applications. This has also led to the replacement of film projectors with digital projection . Despite this, some filmmakers continue to opt for film stock as
1155-479: A 12-year period, including the fast-paced Rowan & Martin's Laugh-In . With the variable quality of Kinescopes, networks looked towards alternative methods to replace them with a higher degree of quality. Programs originally shot with film cameras (as opposed to kinescopes) were also used in television's early years, although they were generally considered inferior to the big-production live programs because of their lower budgets and loss of immediacy. In 1951,
1320-475: A backup reference copy of a program. Another occasional use of telerecording into the late 1980s was by documentary makers working in 16 mm film who wished to include a videotape-sourced excerpt in their work, although such use was again rare. In other territories, film telerecordings stopped being produced after the introduction of videotape. In Czechoslovakia, the first videotape recorders (Machtronics MVR-15) were introduced in 1966 but soon were replaced by
1485-429: A camera must expose one frame of film for exactly 1/30th or 1/25th of a second, the time in which one frame of video is transmitted, and move to another frame of film within the small interval of 1/120th of a second. Motion picture film Film stock is an analog medium that is used for recording motion pictures or animation . It is recorded on by a movie camera , developed , edited , and projected onto
1650-482: A characteristic white glow around black objects (and a corresponding black glow around white objects), which was a defect of the pick-up. Later vidicon and plumbicon video camera tubes produced much cleaner, more accurate pictures. In 1951, singer Bing Crosby ’s company Bing Crosby Enterprises made the first experimental magnetic video recordings ; however, the poor picture quality and very high tape speed meant it would be impractical to use. In 1956, Ampex introduced
1815-446: A color reversal stock, called Monopack, for location shooting in 1941; it was ultimately a 35 mm version of Kodachrome that could be used in standard motion picture cameras. Eastman Kodak introduced their first 35mm color negative stock, Eastman Color Negative film 5247, in 1950. A higher quality version in 1952, Eastman Color Negative film 5248, was quickly adopted by Hollywood for color motion picture production, replacing both

The term originally referred to the cathode-ray tube (CRT) used in television receivers , as named by inventor Vladimir K. Zworykin in 1929. Hence, the recordings were known in full as kinescope films or kinescope recordings . RCA was granted a trademark for
2145-414: A fragile paper roll film, with which it was difficult to view a single, continuously moving image without a complex apparatus. The first transparent and flexible film base material was celluloid , which was discovered and refined for photographic use by John Carbutt , Hannibal Goodwin , and George Eastman . Eastman Kodak made celluloid film commercially available in 1889; Thomas Henry Blair, in 1891,
2310-486: A fully panchromatic stock, Pan-23. In 1926, Kodak lowered the price of panchromatic stock to parity with its orthochromatic offering and the panchromatic stock began to overtake the orthochromatic stock's market share within a few years. As similar panchromatic film stocks were also manufactured by Agfa and Pathé, making the shift to panchromatic stocks largely complete by 1928, Kodak discontinued orthochromatic stock in 1930. Experiments with color films were made as early as
2475-472: A handful of episodes , such as with the early television work of comedian Ernie Kovacs , and the original version of Jeopardy! hosted by Art Fleming . Another purpose of Kinescopes involved satisfying show sponsors. Kinescopes sometimes would be sent to the advertising agency for the sponsor of a show so that the ad agency could determine whether or not the sponsor's ads appeared properly. Due to this practice, some kinescopes have actually been discovered in
2640-464: A high-tech name (and avoiding the word kinescope) to distinguish the process from conventional film photography. Nonetheless, the advances in picture quality were, at the time, a major step ahead. By capturing more than 800 lines of resolution at 25 frame/s, raw tape could be converted to film via kinescope recording with sufficient enhanced resolution to allow big-screen enlargement. The 1960s productions used Marconi image orthicon video cameras, which have
2805-454: A higher quality result. For overseas sales, 16 mm film would be used, as it was cheaper. Although domestic use of telerecording in the UK for repeat broadcasts dropped off sharply after the move to colour in the late 1960s, 16 mm black and white film telerecordings were still being offered for sale by British broadcasters well into the 1970s. Telerecording was still being used internally at

The United Kingdom had an estimated population of over 68.2 million people in 2023. The capital and largest city of both England and the United Kingdom is London , whose wider metropolitan area is
3135-569: A laser film printer known as a film recorder . Due to the specialized nature of the exposure and the higher degree of control afforded by the film lab equipment, these intermediate and release stocks are specially designed solely for these applications and are generally not feasible for camera shooting. Because intermediates only function to maintain the image information accurately across duplication, each manufacturer tends to only produce one or two different intermediate stocks. Similarly, release print stocks usually are available only in two varieties:
3300-399: A leading role in the movement to abolish slavery worldwide through the blockade of Africa and pressing other nations to end their trade with a series of treaties. In 1800 the parliaments of Great Britain and Ireland each passed an Act of Union, uniting the two kingdoms and creating the United Kingdom of Great Britain and Ireland on 1 January 1801. After the defeat of France at the end of
3465-496: A medium of choice for aesthetic reasons. Movies produced entirely on photochemical film or with a combination of analog and digital methods are a minority, but maintain a stable presence among both arthouse and mainstream film releases. However, digital formats are sometimes deliberately altered to achieve a film look , such as adding film grain or other noise for artistic effect.

Cellulose nitrate, because of its unstable chemistry, eventually breaks down, releasing nitric acid, further catalyzing the decomposition. In the final stage of celluloid decomposition, the film has turned into a rust-like powder. Likewise, tri-acetate stock is also vulnerable to deterioration. Because of the small gauge of

During this time, Canada , Australia and New Zealand were granted self-governing dominion status. At the turn of the century, Britain's industrial dominance became challenged by the German Empire and the United States . The Edwardian era saw social reform and home rule for Ireland become important domestic issues, while
3960-468: A positive (showing the same densities and colors as the subject) or negative image (with dark highlights, light shadows, and, in principle, complementary colors). The first films were darkened by light: negative films. Later films that produce a positive image became known as reversal films ; processed transparent film of this type can be projected onto a screen. Negative images need to be transferred onto photographic paper or other substrate which reverses
4125-459: A result of a shortage of workers in the 1950s, the government encouraged immigration from Commonwealth countries . In the following decades, the UK became a more multi-ethnic society. Despite rising living standards in the late 1950s and 1960s, the UK's economic performance was less successful than many of its main competitors such as France, West Germany and Japan. The UK was the first democratic nation to lower its voting age to 18 in 1969. In
4290-402: A screen using a movie projector . It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but
4455-420: A second time until recording methods improved. Eventually, telerecordings would be used to preserve a program for repeat showings. In the UK, telerecordings continued to be made after the introduction of commercial broadcast videotape in 1958 as they possessed several distinct advantages. Firstly, they were easier to transport and more durable than videotape. Secondly, they could be used in any country regardless of
4620-476: A separate soundtrack and then sound-on-film to print the soundtrack on the film itself. All plastic is subject to deterioration through physical or chemical means, and thus, motion picture film is at risk for the same reason. Films deteriorate over time, which can damage individual frames or even lead to the entire film being destroyed. Cellulose nitrate, cellulose diacetate and triacetate are known to be unstable media: improperly preserved film can deteriorate in
4785-811: A series of connected wars (including the English Civil War ) which led to the temporary overthrow of the monarchy, with the execution of King Charles I , and the establishment of the short-lived unitary republic of the Commonwealth of England , Scotland and Ireland. Although the monarchy was restored , the Interregnum along with the Glorious Revolution of 1688 and the subsequent Bill of Rights 1689 in England and Claim of Right Act 1689 in Scotland ensured that, unlike much of
4950-502: A standard option. Panchromatic film stock increased costs and no motion pictures were produced on it in their entirety for several years. The cross-cutting between panchromatic and orthochromatic stocks caused continuity problems with costume tones and panchromatic film was often avoided. Orthochromatic film remained dominant until the mid-1920s due to Kodak's lack of competition in the panchromatic market. In 1925, Gevaert introduced an orthochromatic stock with limited color sensitivity and
5115-400: A stock is its film speed , determined by ASA or its sensitivity to light listed by a measurement on the raw stock which must be chosen with care. Speed determines the range of lighting conditions under which the film can be shot, and is related to granularity and contrast, which influence the look of the image. The stock manufacturer will usually give an exposure index (EI) number equal to

Eastman Kodak introduced a non-flammable 35 mm film stock in 1909. The plasticizers used to make the film flexible evaporated quickly, making the film dry and brittle, causing splices to part and perforations to tear. In 1911

Although this episode was originally produced and broadcast in color, the black and white film was the only surviving copy of the episode following the wiping of the original videotape. However, the telerecording process left color information in
12540-755: The Brittonic area mainly to what was to become Wales , Cornwall and, until the latter stages of the Anglo-Saxon settlement, the Hen Ogledd (northern England and parts of southern Scotland). Most of the region settled by the Anglo-Saxons became unified as the Kingdom of England in the 10th century. Meanwhile, Gaelic speakers in north-west Britain (with connections to the north-east of Ireland and traditionally supposed to have migrated from there in
12705-502: The Commonwealth that had started a television service. A Royal Air Force aircraft would fly the telerecording from the UK to Canada, where it would be broadcast over the whole North American network. Prior to the introduction of videotape in 1956, kinescopes were the only way to record television broadcasts, or to distribute network television programs that were broadcast live from originating cities to stations not connected to
12870-830: The Manhattan Project whose task was to build an atomic weapon. Once built, it was decided, with British consent, to use the weapon against Japan. The UK was one of the Big Three powers (along with the US and the Soviet Union) who met to plan the post-war world ; it drafted the Declaration by United Nations with the United States and became one of the five permanent members of the United Nations Security Council . It worked closely with
13035-476: The Name of Great Britain". The term "United Kingdom" has occasionally been used as a description for the former Kingdom of Great Britain , although its official name from 1707 to 1800 was simply "Great Britain". The Acts of Union 1800 formed the United Kingdom of Great Britain and Ireland . Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as
13200-623: The Normans conquered England . With the end of the Wars of the Roses the English state stabilised and began to grow in power, resulting by the 16th century in the annexation of Wales , the domination of Scotland , and the establishment of the British Empire . Over the course of the 17th century, the role of the British monarchy was reduced, particularly as a result of the English Civil War . In 1707,
13365-567: The Pacific Time Zone. But as an article in American Cinematographer explained, In the beginning there was a very definite reason for the decision of Desilu Productions to put I Love Lucy on film instead of doing it live and having kinescope recordings carry it to affiliate outlets of the network. The company was not satisfied with the quality of kinescopes. It saw that film, produced especially for television,
13530-716: The Scottish electorate voting by 55.3 to 44.7% to remain part of the United Kingdom. In 2016, 51.9 per cent of voters in the United Kingdom voted to leave the European Union . The UK left the EU in 2020. On 1 May 2021, the EU–UK Trade and Cooperation Agreement came into force. The COVID-19 pandemic had a severe impact on the UK's economy , caused major disruptions to education and had far-reaching impacts on society and politics in 2020 and 2021. The United Kingdom
13695-556: The Second World War damaged Britain's economic power and a global wave of decolonisation led to the independence of most British colonies. The United Kingdom is a constitutional monarchy and parliamentary democracy . The UK has three distinct jurisdictions: England and Wales , Scotland , and Northern Ireland . Since 1999, Scotland, Wales and Northern Ireland have their own governments and parliaments which control various devolved matters. A developed country ,
13860-501: The UK has the world's sixth-largest economy by nominal gross domestic product (GDP). It is a nuclear state , and is ranked fifth globally in military expenditure . The UK has been a permanent member of the UN Security Council since its first session in 1946. It is a member of the Commonwealth of Nations , Council of Europe , G7 , OECD , NATO , Five Eyes , AUKUS and CPTPP . British influence can be observed in
14025-484: The UK in 2023 is estimated to be 3.25 million hectares, which represents 13% of the total land area in the UK. Most of the United Kingdom has a temperate climate, with generally cool temperatures and plentiful rainfall all year round. The temperature varies with the seasons seldom dropping below 0 °C (32 °F ) or rising above 30 °C (86 °F). Some parts, away from the coast, of upland England, Wales, Northern Ireland and most of Scotland, experience
14190-961: The UK into lowland and upland areas. Lowland areas include Cornwall , the New Forest , the South Downs and the Norfolk Broads . Upland areas include the Lake District , the Pennines , the Yorkshire Dales , Exmoor , and Dartmoor . The main rivers and estuaries are the Thames , Severn , and the Humber . England's highest mountain is Scafell Pike , at 978 metres (3,209 ft) in the Lake District; its largest island
14355-402: The United Kingdom and that elsewhere "British government" is used at least as frequently as "United Kingdom government". The UK Permanent Committee on Geographical Names recognises "United Kingdom", "UK" and "U.K." as shortened and abbreviated geopolitical terms for the United Kingdom of Great Britain and Northern Ireland in its toponymic guidelines; it does not list "Britain" but notes that "it
14520-411: The United Kingdom is 1339.7 hours, which is just under 30% of the maximum possible. The hours of sunshine vary from 1200 to about 1580 hours per year, and since 1996 the UK has been and still is receiving above the 1981 to 2010 average hours of sunshine. Climate change has a serious impact on the country. A third of food price rise in 2023 is attributed to climate change. As of 2022, the United Kingdom
14685-436: The United Kingdom use several different terms to describe their national identity and may identify themselves as being British , English , Scottish , Welsh , Northern Irish , or Irish ; or as having a combination of different national identities. Settlement by Cro-Magnons of what was to become the United Kingdom occurred in waves beginning by about 30,000 years ago. The island has been continuously inhabited only since
14850-685: The United Kingdom. The 1928 Equal Franchise Act gave women electoral equality with men in national elections. Strikes in the mid-1920s culminated in the General Strike of 1926 . Britain had still not recovered from the effects of the First World War when the Great Depression (1929–1932) led to considerable unemployment and hardship in the old industrial areas, as well as political and social unrest with rising membership in communist and socialist parties. A coalition government
15015-640: The United States to establish the IMF , World Bank and NATO . The war left the UK severely weakened and financially dependent on the Marshall Plan , but it was spared the total war that devastated eastern Europe. In the immediate post-war years, the Labour government under Clement Attlee initiated a radical programme of reforms, which significantly impacted British society in the following decades . Major industries and public utilities were nationalised ,
15180-914: The United States, and by 1955 that number had increased to 2,500 per week for CBS. By 1954 the television industry's film consumption surpassed that of all of the Hollywood studios combined. After the network of coaxial cable and microwave relays carrying programs to the West Coast was completed in September 1951, CBS and NBC instituted a hot kinescope process in 1952, where shows being performed in New York were transmitted west, filmed on two kinescope machines in 35 mm negative and 16 mm reversal film (the latter for backup protection) in Los Angeles, rushed to film processing, and then transmitted from Los Angeles three hours later for broadcast in
15345-521: The acquisition and settlement of overseas colonies , particularly in North America and the Caribbean. Though previous attempts at uniting the two kingdoms within Great Britain in 1606, 1667, and 1689 had proved unsuccessful, the attempt initiated in 1705 led to the Treaty of Union of 1706 being agreed and ratified by both parliaments. On 1 May 1707, the Kingdom of Great Britain was formed,
15510-411: The archives is in the form of a telerecording, along with the vast majority of existing 1960s output. Videotape was expensive and could be wiped and re-used; film was cheaper, smaller, and in practice more durable. Only a very small proportion of British television from the black-and-white era survives at all. As the BBC has taken stock of the large gaps in its archive and sought to recover as much of
15675-460: The cinematic footage made during the same event by Leni Riefenstahl for her film Olympia ), a number of Nuremberg Rallies , or official state visits (such as Benito Mussolini 's) were shot directly on 35 mm instead and transmitted over the air as a television signal, with only a two minutes' delay from the original event, by means of the so-called Zwischenfilmverfahren (see intermediate film system ) from an early outside broadcast van on
15840-453: The commonality of Edison's and Lumière's cameras . Consumers usually purchased unperforated film and had to punch it by perforators that were often imprecise, causing difficulty in making prints for the opposite perforation format. In 1908, the perforators began to be made by Bell and Howell . Eastman Kodak used the Bell and Howell machine to perforate its films. In 1909, Edison's organization of
16005-764: The compensation after each light reading. Another important quality of color film stock in particular is its color balance , which is defined by the color temperature at which it accurately records white. Tungsten lighting is defined at 3200 K, which is considered "warmer" in tone and shifted towards orange; daylight is defined at 5600 K, which is considered "colder" and shifted towards blue. This means that unfiltered tungsten stock will look normal shot under tungsten lights, but blue if shot during daylight. Conversely, daylight stock shot in daylight will look normal, but orange if shot under tungsten lights. Color temperature issues such as these can be compensated for by other factors such as lens filters and color gels placed in front of
16170-418: The crystals sensitive to different colors. Typically the blue-sensitive layer is on top, followed by the green and red layers. During development, the exposed silver salts are converted to metallic silver, just as with black-and-white film. But in a color film, the by-products of the development reaction simultaneously combine with chemicals known as color couplers that are included either in the film itself or in
16335-622: The daily five-minute syndicated series Les Paul & Mary Ford At Home in 1954–55), but with the introduction of a practical videotape recorder only one year away, the Electronicam system never saw widespread use. The DuMont network did not survive into the era of videotape, and in order to gain clearances for its programs, was heavily dependent on kinescopes, which it called Teletranscriptions. Attempts were made for many years to take television images, convert them to film via kinescope, then project them in theatres for paying audiences. In
16500-736: The decades-long process of European integration , the UK was a founding member of the Western European Union , established with the London and Paris Conferences in 1954. In 1960 the UK was one of the seven founding members of the European Free Trade Association (EFTA), but in 1973 it left to join the European Communities (EC). In a 1975 referendum 67% voted to stay in it. When the EC became
16665-439: The developer solution to form colored dyes. Because the by-products are created in direct proportion to the amount of exposure and development, the dye clouds formed are also in proportion to the exposure and development. Following development, the silver is converted back to silver salts in the bleach step . It is removed from the film in the fix step and is sometimes recovered for subsequent use or sale. Fixing leaves behind only
16830-465: The early 1970s by which time programs were being videotaped in color. Most, if not all, recordings from the 405-line era have long since been lost as have many from the introduction of 625-line video to the early days of color. Consequently, the majority of British shows that still exist before the introduction of color, and a number thereafter, do so in the form of these telerecordings. A handful of shows, including some episodes of Doctor Who and most of
16995-483: The eastern parts are the driest. Atlantic currents, warmed by the Gulf Stream , bring mild winters, especially in the west where winters are wet and even more so over high ground. Summers are warmest in the southeast of England and coolest in the north. Heavy snowfall can occur in winter and early spring on high ground, and occasionally settles to great depth away from the hills. The average total annual sunshine in
17160-426: The emulsion, retaining a large market share. Lumière reformulated its stock to match the speed of Eastman film, naming it 'Etiquette Violette' (Violet Label). Blair sold his English company to Pathé in 1907 and retired to the US. Pathé began to supplement its operation in 1910 by purchasing film prints, stripping the emulsion from the film base and re-coating it. 35mm film began to become the dominant gauge because of
17325-407: The expensive three-strip Technicolor process and Monopack. There are several variables in classifying stocks; in practice, one orders raw stock by a code number, based on desired sensitivity to light. A piece of film consists of a light-sensitive emulsion applied to a tough, transparent base , sometimes attached to anti-halation backing or "rem-jet" layer (now only on camera films). Originally
17490-459: The few surviving DuMont kinescopes, with the UCLA Film and Television Archive having collected over 300 for preservation. In September 2010, a kinescope of game 7 of the 1960 World Series was found in the wine cellar of Bing Crosby. The game was thought lost forever but was preserved due to Crosby's superstition about watching the game live. The film was transferred to DVD and was broadcast on
17655-423: The film, owners of home-made films often find that their film can become shrunken and brittle to the point where the film is unwatchable in the space of a few years. In general, decaying acetate film breaks down into acetic acid , and similar to celluloid decomposition, leads to an auto-catylictic breakdown of the base that cannot be reversed. The result of the acetic acid released is a strong odor of vinegar , which
17820-507: The film. A resin backing was used on the film, which rendered the film too opaque to allow focusing through the back of the film, a common technique for many cameras of that era. The X-back stock was popular on the east coast of the US. Other manufacturers were established in the 1920s, including American E.I. Dupont de Nemours in 1926 and Belgian Gevaert in 1925. Panchromatic film stock became more common. Created in 1913 for use in early color film processes such as Kinemacolor , panchromatic
17985-527: The first commercial Quadruplex videotape recorder, followed in 1958 by a colour model. Offering high quality and instant playback at a much lower cost, Quadruplex tape quickly replaced kinescope as the primary means of recording television broadcasts. In the late 1960s, U.S. television networks continued to make kinescopes of their daytime dramas available, many of which still aired live during that time period, for their smaller network affiliates that did not yet have videotape capability but wished to time-shift
18150-404: The first industrialised country and was the world's foremost power for the majority of the 19th and early 20th centuries, particularly during the " Pax Britannica " between 1815 and 1914. At its height in the 1920s, the British Empire encompassed almost a quarter of the world's landmass and population, and was the largest empire in history . However, its involvement in the First World War and
18315-746: The first series of Adam Adamant Lives! , were deliberately telerecorded for ease of editing rather than being videotaped. In September 1947, Eastman Kodak introduced the Eastman Television Recording Camera, in cooperation with DuMont Laboratories and NBC , for recording images from a television screen under the trademark "Kinephoto". NBC, CBS , and DuMont set up their main kinescope recording facilities in New York City, while ABC chose Chicago . By 1951, NBC and CBS were each shipping out some 1,000 16 mm kinescope prints each week to their affiliates across
18480-594: The first year, Britain and its Empire continued the war against Germany. Churchill engaged industry, scientists and engineers to support the government and the military in the prosecution of the war effort. In 1940, the Royal Air Force defeated the German Luftwaffe in the Battle of Britain . Urban areas suffered heavy bombing during the Blitz . The Grand Alliance of Britain, the United States and
18645-577: The form of chroma dots in the frames of the film; using a specially designed computer program, these chroma dots were used to bring out the original color information, which as then applied to the film, allowing the color to be restored to the episode. The restored version of Room at the Bottom was broadcast on 13 December 2008, the first time it had been seen in color since May 1970. NTSC television images are scanned at roughly 60 Hz , with two interlaced fields per frame, displayed at 30 frames per second . A kinescope must be able to convert
18810-587: The formal control it exerted over its own colonies, British dominance of much of world trade meant that it effectively controlled the economies of regions such as East Asia and Latin America . Throughout the Victorian era , political attitudes favoured free trade and laissez-faire policies. Beginning with the Great Reform Act in 1832, Parliament gradually widened the voting franchise , with
18975-419: The formed color dyes, which combine to make up the colored visible image. Later color films, like Kodacolor II , have as many as 12 emulsion layers, with upwards of 20 different chemicals in each layer. Photographic film and film stock tend to be similar in composition and speed, but often not in other parameters such as frame size and length. Early motion picture experiments in the 1880s were performed using
19140-762: The global hegemon and adopted the role of global policeman. From 1853 to 1856, Britain took part in the Crimean War , allied with the Ottoman Empire against Tsarist Russia , participating in the naval battles of the Baltic Sea known as the Åland War in the Gulf of Bothnia and the Gulf of Finland , among others. Following the Indian Rebellion in 1857 , the British government led by Lord Palmerston assumed direct rule over India . Alongside
19305-436: The highly flammable cellulose nitrate was used. In the 1930s, film manufacturers introduced " safety film " with a cellulose triacetate plastic base. All amateur film stocks were safety film, but the use of nitrate persisted for professional releases. Kodak discontinued the manufacture of nitrate base in 1951, and the industry transitioned entirely to safety film in 1951 in the United States and by 1955 internationally. Since
19470-610: The image again, producing a final positive image. Creating a positive image from a negative film can also be done by scanning the negative to create a computer file which can then be reversed by software . Different emulsions and development processes exist for a variety of image recording possibilities: the two most common of which are black and white, and color. However, there are also variant types, such as infrared film (in black and white or false color ); specialist technical films, such as those used for X-rays ; and obsolete processes, such as orthochromatic film. Generally, however,
19635-408: The improvements were in granularity and sharpness. Film stock manufacturers began to diversify their products. Each manufacturer had previously offered one negative stock (usually orthochromatic) and one print stock. In 1920, a variant of Type F film known as X-back was introduced to counteract the effects of static electricity on the film, which can cause sparking and create odd exposure patterns on
19800-597: The incident is dramatized in Jack Rosenthal 's 1986 television play The Fools on the Hill . Some of the surviving live transmissions of the Nazi German television station Fernsehsender Paul Nipkow , dating as far back as the 1930s, were recorded by pointing a 35 mm camera to a receiver's screen, although most surviving Nazi live television programs such as the 1936 Summer Olympics (not to be confused with
19965-525: The kinescopes, however, was replaced with high fidelity sound that had been recorded simultaneously either on transcription discs or magnetic tape . In the mid-1990s, Edie Adams , wife of Ernie Kovacs, claimed that so little value was given to the kinescope recordings of the DuMont Television Network that after the network folded in 1956 its entire archive was dumped into upper New York bay. Today however, efforts are made to preserve
20130-403: The kingdoms of England, Scotland and Ireland were united in a personal union when James VI, King of Scots , inherited the crowns of England and Ireland and moved his court from Edinburgh to London; each country nevertheless remained a separate political entity and retained its separate political, legal, and religious institutions. In the mid-17th century, all three kingdoms were involved in
20295-581: The largest in Western Europe , with a population of 14.9 million. The cities of Edinburgh , Cardiff , and Belfast are the national capitals of Scotland, Wales, and Northern Ireland, respectively. The lands of the UK have been inhabited continuously since the Neolithic . In AD 43 the Roman conquest of Britain began; the Roman departure was followed by Anglo-Saxon settlement . In 1066,
20460-408: The last retreat of the ice around 11,500 years ago. By the end of the region's prehistoric period , the population is thought to have belonged largely to a culture termed Insular Celtic , comprising Brittonic Britain and Gaelic Ireland . The Roman conquest , beginning in 43 AD, and the 400-year rule of southern Britain , was followed by an invasion by Germanic Anglo-Saxon settlers, reducing
20625-485: The late 1990s, almost all release prints have used polyester film stock. The emulsion consists of silver halide grains suspended in a gelatin colloid; in the case of color film, there are three layers of silver halide, which are mixed with color couplers and interlayers that filter specific light spectra. These end up creating yellow, cyan , and magenta layers in the negative after development. Development chemicals applied to an appropriate film can produce either
20790-584: The late 19th century, but practical color film was not commercially viable until 1908, and for amateur use when Kodak introduced Kodachrome for 16 mm in 1935 and 8 mm in 1936. Commercially successful color processes used special cameras loaded with black-and-white separation stocks rather than color negative. Kinemacolor (1908–1914), Technicolor processes 1 through 4 (1917–1954), and Cinecolor used one, two or three strips of monochrome film stock sensitized to certain primary colors or exposed behind color filters in special cameras. Technicolor introduced
20955-409: The legal and political systems of many of its former colonies , and British culture remains globally influential, particularly in language , literature , music and sport . English is the world's most widely spoken language and the third-most spoken native language . The Acts of Union 1707 declared that the Kingdom of England and Kingdom of Scotland were "United into One Kingdom by
21120-492: The lights. The color temperature of a film stock is generally indicated next to the film speed number — e.g. 500T stock is color film stock with an ASA of 500 and balanced for tungsten light; 250D would have an ASA of 250 and be balanced for daylight. While black-and-white film has no color temperature itself, the silver halide grains themselves tend to be slightly more responsive to blue light, and therefore will have daylight and tungsten speeds — e.g. Kodak's Double-X stock
21285-530: The local cultures. Subsequent medieval English kings completed the conquest of Wales and tried unsuccessfully to annex Scotland . Asserting its independence in the 1320 Declaration of Arbroath , Scotland maintained its independence thereafter, albeit in near-constant conflict with England . In 1215 the Magna Carta was the first document to state that no government was above the law, that citizens have rights protecting them and that they were entitled to
21450-432: The major American film studios returned to using nitrate stock. More amateur formats began to use acetate-based film, and several, including Kodak's own 16 mm format, were designed specifically to be manufactured with safety base. Kodak released Cine Negative Film Type E in 1916 and Type F (later known as Negative Film Par Speed Type 1201) in 1917. As both of these orthochromatic films were no faster than previous offerings,
21615-680: The major part of the British Isles archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and some smaller surrounding islands. It lies between the North Atlantic Ocean and the North Sea with the southeast coast coming within 22 miles (35 km) of the coast of northern France, from which it is separated by the English Channel . The Royal Greenwich Observatory in London
21780-674: The mid-1920s, most of the British population could listen to BBC radio programmes. Experimental television broadcasts began in 1929 and the first scheduled BBC Television Service commenced in 1936. The rise of Irish nationalism , and disputes within Ireland over the terms of Irish Home Rule , led eventually to the partition of the island in 1921. A period of conflict in what is now Northern Ireland occurred from June 1920 until June 1922. The Irish Free State became independent, initially with Dominion status in 1922, and unambiguously independent in 1931 . Northern Ireland remained part of
21945-473: The mid-1960s, Producer/entrepreneur H. William "Bill" Sargent, Jr. used conventional analog Image Orthicon video camera tube units, shooting in the B&;W 819-line interlaced 25fps French video standard, using modified high-band quadruplex VTRs to record the signal. The promoters of Electronovision (not to be confused with Electronicam ) gave the impression that this was a new system created from scratch, using
22110-464: The missing material as possible, many recovered programs, have been returned from the 1980s onwards as telerecordings held by foreign broadcasters or private film collectors. Many of these surviving telerecorded programs, such as episodes of Doctor Who , Steptoe and Son and Till Death Us Do Part continue to be transmitted on satellite television stations such as UKTV Gold , and many such programs have been released on VHS and DVD . In 2008,
22275-428: The need for hot kines , the television networks continued to use kinescopes in the double system method of videotape editing. It was impossible to slow or freeze frame a videotape at that time, so the unedited tape would be copied to a kinescope, and edited conventionally. The edited kinescope print was then used to conform the videotape master. More than 300 videotaped network series and specials used this method over
22440-465: The network programming. Some of these programs aired up to two weeks after their original dates, particularly in Alaska and Hawaii . Many episodes of programs from the 1960s survive only through kinescoped copies. In Australia, kinescopes were still being made of some evening news programs as late as 1977, if they were recorded at all. A recording of a 1975 episode of Australian series This Day Tonight
22605-493: The network, or to stations that wished to show a program at a time different than the network broadcast. Although the quality was less than desirable, television programs of all types from prestigious dramas to regular news shows were handled in this manner. Even after the introduction of videotape, the BBC and the ITV companies made black and white kinescopes of selected programs for international sales and continued to do so until
22770-463: The only part of the island of Ireland within the United Kingdom, the name was changed in 1927 to the "United Kingdom of Great Britain and Northern Ireland". Although the United Kingdom is a sovereign country, England, Scotland, Wales and Northern Ireland are also widely referred to as countries . The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom. Some statistical summaries, such as those for
22935-402: The outbreak of World War II . A BBC executive, Cecil Madden , recalled filming a production of The Scarlet Pimpernel in this way, only for film director Alexander Korda to order the burning of the negative as he owned the film rights to the book, which he felt had been infringed. While there is no written record of any BBC Television production of The Scarlet Pimpernel during 1936–1939,
23100-595: The process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph . In addition to visible light, all films are sensitive to X-rays and high-energy particles . Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into
23265-504: The rest of Europe, royal absolutism would not prevail, and a professed Catholic could never accede to the throne. The British constitution would develop on the basis of constitutional monarchy and the parliamentary system . With the founding of the Royal Society in 1660, science was greatly encouraged. During this period, particularly in England, the development of naval power and the interest in voyages of discovery led to
23430-587: The result of the Acts of Union 1707 between the Kingdom of England and Kingdom of Scotland . In the 18th century, cabinet government developed under Robert Walpole , in practice the first prime minister (1721–1742). A series of Jacobite uprisings sought to remove the Protestant House of Hanover from the throne and restore the Catholic House of Stuart . The Jacobites were finally defeated at
23595-482: The short duration of a 16 mm film magazine, was that a large opaque frame had to be placed in front of the TV set in order to block out any stray reflections, making it impossible to watch the set normally while filming. It is not known if any recordings made using this equipment still exist. British broadcasters used telerecordings for domestic purposes well into the 1960s, with 35 mm film usually used as it produced
23760-459: The show was kinescoped for later rebroadcast for the West Coast. Per his contract, he would receive one copy of each broadcast, which he kept in his vault, and only released them to the public (on home video) shortly before his death in 1987. Milton Berle sued NBC late in his life, believing the kinescopes of a major portion of his programs were lost. However, the programs were later found in
23925-461: The show was originally broadcast on BBC TV it was 60 minutes in length and also included performances from Winifred Atwell , Evelyn Dove , Cyril Blake and his Calypso Band, Edric Connor and Mable Lee , and was produced by Eric Fawcett. The six-minute footage of Miss Hall is all that survives of the show. From the following month, the wedding of Princess Elizabeth to Prince Philip also survives, as do various early 1950s productions such as It
24090-572: The site. According to a 1949 film produced by RCA , silent films had been made of early experimental telecasts during the 1930s. The films were produced by aiming a camera at television monitors – at a speed of eight frames per second, resulting in somewhat jerky reproductions of the images. By the mid-1940s, RCA and NBC were refining the filming process and including sound; the images were less jerky but still somewhat fuzzy. By early 1946, television cameras were being attached to American guided missiles to aid in their remote steering. Films were made of
24255-539: The stars and producers of the Hollywood-based television series I Love Lucy , Desi Arnaz and Lucille Ball , decided to film the show directly onto 35 mm film using the three-camera system , instead of broadcasting it live. Normally, a live program originating from Los Angeles would be performed live in the late afternoon for the Eastern Time Zone and seen on a kinescope three hours later in
24420-413: The storage areas of some of these older advertising agencies or in the storage areas of the program sponsors themselves. Certain performers or production companies would require that a kinescope be made of every television program. Such is the case with performers Jackie Gleason and Milton Berle , for whom nearly complete program archives exist. As Jackie Gleason's program was broadcast live in New York,
24585-460: The studio TV cameras had built-in 35 mm film cameras which shared the same optical path. An Electronicam technician threw switches to mark the film footage electronically, identifying the camera takes called by the director. The corresponding film segments from the various cameras then were combined by a film editor to duplicate the live program. The "Classic 39" syndicated episodes of The Honeymooners were filmed using Electronicam (as well as
24750-456: The television broadcasting standard, which was not true of videotape. Later, the system could be used to make black-and-white copies of color programs for sale to television stations that were not yet broadcasting in color. The system was largely used for black-and-white reproduction. Although some color telerecordings were made, they were generally in the minority as by the time color programs were widely needed for sale, video standards conversion
24915-556: The television images they transmitted for further evaluation of the target and the missile's performance. The first known surviving example of the telerecording process in Britain is from October 1947, showing the singer Adelaide Hall performing at the RadiOlympia event. Hall sings " Chi-Baba, Chi-Baba (My Bambino Go to Sleep) " and " I Can't Give You Anything But Love ", as well as accompanying herself on ukulele and dancing. When
25080-414: The term (for its CRT) in 1932; it voluntarily released the term to the public domain in 1950. The General Electric laboratories in Schenectady, New York experimented with making still and motion picture records of television images in 1931. There is anecdotal evidence that the BBC experimented with filming the output of the television monitor before its television service was suspended in 1939 due to
25245-454: The time equivalent of one field of television (131.25 lines). In the British 405-line television system , the French 819-line television system and the greater European 625-line television system , television ran at 25 frames—or more correctly, 50 fields—per second, so the film camera would also be run at 25 frames per second rather than the cinematic film standard of 24 frames. Therefore, in order to maintain successful kinescope photography,
25410-436: The twelve NUTS 1 regions , refer to Scotland, Wales and Northern Ireland as "regions". Northern Ireland is also referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice often revealing one's political preferences". The term "Great Britain" conventionally refers to the island of Great Britain, or politically to England, Scotland and Wales in combination. It
25575-441: The use of kinescopes for all of these purposes. Kinescopes were the only practical way to preserve live television broadcasts prior to videotape. Typically, the term can refer to the process itself, the equipment used for the procedure (a movie camera mounted in front of a video monitor, and synchronized to the monitor's scanning rate), or a film made using the process. Film recorders are similar, but record source material from
25740-400: The vast majority of stock used today is "normal" (visible spectrum) color, although "normal" black and white also commands a significant minority percentage. Film is also classified according to its gauge and the arrangement of its perforations — gauges range from 8 mm to 70 mm or more, while perforations may vary in shape, pitch, and positioning. The film is also distinguished by how it
25905-416: Was chosen as the defining point of the Prime Meridian at the International Meridian Conference in 1884. The United Kingdom lies between latitudes 49° and 61° N , and longitudes 9° W and 2° E . Northern Ireland shares a 224-mile (360 km) land boundary with the Republic of Ireland. The coastline of Great Britain is 11,073 miles (17,820 km) long, though measurements can vary greatly due to
26070-458: Was easier and higher quality and the price of videotape had become much reduced. Before videotape became the exclusive recording format during the early to mid-1980s, any (color) video recordings used in documentaries or filmed program inserts were usually transferred onto film. In the 1950s a home telerecording kit was introduced in Britain, allowing enthusiasts to make 16 mm film recordings of television programs. The major drawback, apart from
26235-402: Was first used in a black-and-white film for exterior sequences in Queen of the Sea (1918) and originally available as a special order product. The stock's increased sensitivity to red light made it an attractive option for day for night shooting. Kodak financed a feature in 1922, shot entirely with panchromatic stock, The Headless Horseman , to promote the film when Kodak introduced it as
26400-404: Was formed in 1931. Nonetheless, "Britain was a very wealthy country, formidable in arms, ruthless in pursuit of its interests and sitting at the heart of a global production system." After Nazi Germany invaded Poland in 1939, Britain entered the Second World War . Winston Churchill became prime minister and head of a coalition government in 1940. Despite the defeat of its European allies in
26565-671: Was his first competitor. The stock had a frosted base to facilitate easier viewing by transmitted light. Emulsions were orthochromatic . By November 1891 William Dickson , at Edison 's laboratory, was using Blair's stock for Kinetoscope experiments. Blair's company supplied film to Edison for five years. Between 1892 and 1893, Eastman experienced problems with production. Because of patent lawsuits in 1893, Blair left his American company and established another in Britain. Eastman became Edison's supplier of film. Blair's new company supplied European filmmaking pioneers, including Birt Acres , Robert Paul , George Albert Smith , Charles Urban , and
26730-604: Was offered in 1889. At first the film was the same as photographic film. By 1916, separate "Cine Type" films were offered. From 1895, Eastman supplied their motion picture roll film in rolls of 65 feet, while Blair's rolls were 75 feet. If longer lengths were needed, the unexposed negative rolls could be cemented in a darkroom , but this was largely undesirable by most narrative filmmakers. The makers of Actuality films were much more eager to undertake this method, however, in order to depict longer actions. They created cemented rolls as long as 1,000 feet. American Mutoscope and Biograph
26895-432: Was the first country in the world to use an approved COVID-19 vaccine , developing its own vaccine through a collaboration between Oxford University and AstraZeneca , which allowed the UK's vaccine rollout to be among the fastest in the world. The total area of the United Kingdom is approximately 94,354 square miles (244,376 km ), with a land area of 93,723 square miles (242,741 km ). The country occupies
27060-400: Was the first known company to use such film for the Jeffries - Sharkey fight on 3 November 1899. As the quantity of film and filmmakers grew, the demand for standardization increased. Between 1900 and 1910, film formats gradually became standardized and film stocks improved. A number of film gauges were made. Eastman increased the length of rolls to 200 feet without major adjustments to
27225-431: Was the only means of ensuring top quality pictures on the home receiver as well as ensuring a flawless show. The I Love Lucy decision introduced reruns to most of the American television audience, and set a pattern for the syndication of TV shows after their network runs. The program director of the DuMont Television Network , James L. Caddigan, devised an alternative – the Electronicam . In this, all
