107-449: Most early filmmakers, such as Thomas Edison , Auguste and Louis Lumière and Georges Méliès , tended not to use close-ups and preferred to frame their subjects in long shots, similar to the stage. Film historians disagree as to the filmmaker who first used a close-up. One of the best claims is for George Albert Smith in Hove , who used medium close-ups in films as early as 1898 and by 1900

214-434: A 16mm film stock, principally as a lower-cost alternative to 35 mm and several camera makers launched models to take advantage of the new market of amateur movie-makers. Thought initially to be of inferior quality to 35 mm, 16 mm cameras continued to be manufactured until the 2000s by the likes of Bolex , Arri , and Aaton . Digital movie cameras do not use analog film stock to capture images, as had been

321-475: A "chunk of it". The representatives decided to give a cubic foot of solid copper weighing 486 pounds with their gratitude inscribed on it in appreciation for his part in the "continuous stimulation in the copper industry". Edison is credited with designing and producing the first commercially available fluoroscope , a machine that uses X-rays to take radiographs . Until Edison discovered that calcium tungstate fluoroscopy screens produced brighter images than

428-401: A $ 50-a-week profit by age 13, most of which went to buying equipment for electrical and chemical experiments. At age 15, in 1862, he saved 3-year-old Jimmie MacKenzie from being struck by a runaway train. Jimmie's father, station agent J. U. MacKenzie of Mount Clemens, Michigan , was so grateful that he trained Edison as a telegraph operator. Edison's first telegraphy job away from Port Huron

535-469: A 16 lens camera in 1887 at his workshop in Leeds . The first 8 lenses would be triggered in rapid succession by an electromagnetic shutter on the sensitive film; the film would then be moved forward allowing the other 8 lenses to operate on the film. After much trial and error, he was finally able to develop a single-lens camera in 1888, which he used to shoot sequences of moving pictures on paper film, including

642-475: A Scottish inventor and employee of Edison, designed the Kinetograph Camera in 1891. The camera was powered by an electric motor and was capable of shooting with the new sprocketed film. To govern the intermittent movement of the film in the camera, allowing the strip to stop long enough so each frame could be fully exposed and then advancing it quickly (in about 1/460 of a second) to the next frame,

749-471: A bid. He was surprised to hear them offer $ 10,000 ($ 269,294 in 2023), which he gratefully accepted. The quadruplex telegraph was Edison's first big financial success, and Menlo Park became the first institution set up with the specific purpose of producing constant technological innovation and improvement. Edison was legally credited with most of the inventions produced there, though many employees carried out research and development under his direction. His staff

856-574: A businessman. Ultimately, his entrepreneurship was central to the formation of some 14 companies, including General Electric , formerly one of the largest publicly traded companies in the world. In 1866, at the age of 19, Edison moved to Louisville, Kentucky , where, as an employee of Western Union , he worked the Associated Press bureau news wire . Edison requested the night shift, which allowed him plenty of time to spend at his two favorite pastimes—reading and experimenting. Eventually,

963-463: A chemistry course at The Cooper Union for the Advancement of Science and Art to support his work on a new telegraphy system with Charles Batchelor . This appears to have been his only enrollment in courses at an institution of higher learning. Thomas Edison began his career as a news butcher , selling newspapers, candy, and vegetables on trains running from Port Huron to Detroit. He turned

1070-436: A child, he became fascinated with technology and spent hours working on experiments at home. Edison developed hearing problems at the age of 12. The cause of his deafness has been attributed to a bout of scarlet fever during childhood and recurring untreated middle-ear infections . He subsequently concocted elaborate fictitious stories about the cause of his deafness. He was completely deaf in one ear and barely hearing in

1177-582: A coiled platinum filament but the high cost of platinum kept the bulb from becoming a commercial success. Many other inventors had also devised incandescent lamps, including Alessandro Volta 's demonstration of a glowing wire in 1800 and inventions by Henry Woodward and Mathew Evans . Others who developed early and commercially impractical incandescent electric lamps included Humphry Davy , James Bowman Lindsay , Moses G. Farmer , William E. Sawyer , Joseph Swan , and Heinrich Göbel . These early bulbs all had flaws such as an extremely short life and requiring

1284-688: A commercially viable electric light bulb on October 21, 1879, Edison developed an electric " utility " to compete with the existing gas light utilities. On December 17, 1880, he founded the Edison Illuminating Company , and during the 1880s, he patented a system for electricity distribution . The company established the first investor-owned electric utility. On September 4, 1882, in Pearl Street , New York City, his 600 kW cogeneration steam-powered generating station, Pearl Street Station 's, electrical power distribution system

1391-458: A complete circle, with gaps between screens through which the projectors illuminate an opposite screen. (See Circle-Vision 360° ) Convex and concave mirrors are used in cameras as well as mirrors. One of the problems in film is synchronizing a sound recording with the film. Most film cameras do not record sound internally; instead, the sound is captured separately by a precision audio device (see double-system recording ). The exceptions to this are

1498-423: A digital timecode directly on the edge of the film itself. However, the most commonly used system at the moment is unique identifier numbers exposed on the edge of the film by the film stock manufacturer (KeyKode is the name for Kodak's system). These are then logged (usually by a computer editing system, but sometimes by hand) and recorded along with audio timecode during editing. In the case of no better alternative,

1605-417: A director, deliberately avoiding close-ups may create in the audience an emotional distance from the subject matter. Close-ups are used for distinguishing main characters. Major characters are often given a close-up when they are introduced as a way of indicating their importance. Leading characters will have multiple close-ups. At the close of Sunset Boulevard (1950), the main character, a faded star under

1712-521: A draftsman and an expert witness in patent litigation, began working for the United States Electric Lighting Company run by Edison's rival Hiram S. Maxim . While working for Maxim, Latimer invented a process for making carbon filaments for light bulbs and helped install broad-scale lighting systems for New York City, Philadelphia, Montreal, and London. Latimer holds the patent for the electric lamp issued in 1881, and

1819-411: A geared drive camera might work for as long as 75 – 90 seconds (at standard speeds). The common film used for these cameras was termed Standard 8 , which was a strip of 16-millimetre wide film which was only exposed down one half during shooting. The film had twice the number of perforations as film for 16 mm cameras and so the frames were half as high and half as wide as 16 mm frames. The film

1926-541: A grooved cylinder. Despite its limited sound quality and that the recordings could be played only a few times, the phonograph made Edison a celebrity. Joseph Henry , president of the National Academy of Sciences and one of the most renowned electrical scientists in the US, described Edison as "the most ingenious inventor in this country... or in any other". In April 1878, Edison traveled to Washington to demonstrate

2033-487: A handclap can work if done clearly and properly, but often a quick tap on the microphone (provided it is in the frame for this gesture) is preferred. One of the most common uses of non-sync cameras is the spring-wound cameras used in hazardous special effects, known as "crash cams". Scenes shot with these have to be kept short or resynchronized manually with the sound. MOS cameras are also often used for second unit work or anything involving slow or fast-motion filming. With

2140-402: A high electric current to operate which made them difficult to apply on a large scale commercially. In his first attempts to solve these problems, Edison tried using a filament made of cardboard, carbonized with compressed lampblack. This burnt out too quickly to provide lasting light. He then experimented with different grasses and canes such as hemp, and palmetto, before settling on bamboo as

2247-738: A laboratory in West Orange, New Jersey , that featured the world's first film studio , the Black Maria . With 1,093 US patents in his name , as well as patents in other countries, Edison is regarded as the most prolific inventor in American history. Edison married twice and fathered six children. He died in 1931 due to complications from diabetes . Thomas Edison was born in 1847 in Milan, Ohio , but grew up in Port Huron, Michigan , after

2354-415: A large part of the market without electrical service. AC companies expanded into this gap. Edison expressed views that AC was unworkable and the high voltages used were dangerous. As George Westinghouse installed his first AC systems in 1886, Thomas Edison struck out personally against his chief rival stating, " Just as certain as death, Westinghouse will kill a customer within six months after he puts in

2461-530: A lesser extent) video games. In response to this, movie director Martin Scorsese started the non-profit organisation The Film Foundation to preserve the use of film in movie making—as many filmmakers feel digital cameras do not convey the depth or emotion that motion-picture film does. Other major directors involved in the organisation include Quentin Tarantino , Christopher Nolan and many more. Most of

2568-401: A moving image to display on a screen. In contrast to the still camera , which captures a single image at a time, the movie camera takes a series of images by way of an intermittent mechanism or by electronic means; each image is a frame of film or video. The frames are projected through a movie projector or a video projector at a specific frame rate (number of frames per second) to show

2675-561: A number of nearby private dwellings, but was shut down in September 1886 as uneconomic, since he was unable to extend the premises. On January 19, 1883, the first standardized incandescent electric lighting system employing overhead wires began service in Roselle, New Jersey . As Edison expanded his direct current (DC) power delivery system, he received stiff competition from companies installing alternating current (AC) systems. From

2782-438: A precise speed. In addition, they're designed to be quiet enough to not hamper sound recording of the scene being shot. Non-sync or " MOS " cameras do not offer these features; any attempt to match location sound to these cameras' footage will eventually result in "sync drift", and the noise they emit typically renders location sound recording useless. To synchronize double-system footage, the clapper board which typically starts

2889-412: A rotating turret. A good quality camera might come with a variety of interchangeable, focusable lenses or possibly a single zoom lens. The viewfinder was normally a parallel sight within or on top of the camera body. In the 1950s and for much of the 1960s these cameras were powered by clockwork motors, again with variations of quality. A simple mechanism might only power the camera for some 30 seconds, while

2996-552: A second patent for the "process of manufacturing carbons" (the filament used in incandescent light bulbs), issued in 1882. On October 8, 1883, the US patent office ruled that Edison's patent was based on the work of William E. Sawyer and was, therefore, invalid. Litigation continued for nearly six years. In 1885, Latimer switched camps and started working with Edison. On October 6, 1889, a judge ruled that Edison's electric light improvement claim for "a filament of carbon of high resistance"

3103-466: A system of any size. He has got a new thing and it will require a great deal of experimenting to get it working practically. " Many reasons have been suggested for Edison's anti-AC stance. One notion is that the inventor could not grasp the more abstract theories behind AC and was trying to avoid developing a system he did not understand. Edison also appeared to have been worried about the high voltage from misinstalled AC systems killing customers and hurting

3210-425: A take is used as a reference point for the editor to match the picture to the sound (provided the scene and take are also called out so that the editor knows which picture take goes with any given sound take). It also permits scene and take numbers and other essential information to be seen on the film itself. Aaton cameras have a system called AatonCode that can "jam sync" with a timecode-based audio recorder and prints

3317-598: Is notably the first US patent for an electronic device due to its use of an Edison effect bulb as an active component . Subsequent scientists studied, applied, and eventually evolved the bulbs into vacuum tubes , a core component of early analog and digital electronics of the 20th century. In 1878, Edison formed the Edison Electric Light Company in New York City with several financiers, including J. P. Morgan , Spencer Trask , and

3424-582: Is now the Czech Republic), opened in 1882, and was the first public building in the world to use Edison's electric lamps. Francis Jehl , Edison's assistant in the invention of the lamp, supervised the installation. In September 2010, a sculpture of three giant light bulbs was erected in Brno, in front of the theater. The first Edison light bulbs in the Nordic countries were installed at the weaving hall of

3531-500: Is registered on 1,093 patents. Edison began his career as an inventor in Newark, New Jersey , with the automatic repeater and his other improved telegraphic devices, but the invention that first gained him wider notice was the phonograph in 1877. This accomplishment was so unexpected by the public at large as to appear almost magical. Edison became known as "The Wizard of Menlo Park". His first phonograph recorded on tinfoil around

3638-586: The Columbia . Although hesitant at first, Edison agreed to Villard's request. Most of the work was completed in May 1880, and the Columbia went to New York City, where Edison and his personnel installed Columbia 's new lighting system. The Columbia was Edison's first commercial application for his incandescent light bulb. The Edison equipment was removed from Columbia in 1895. In 1880, Lewis Latimer ,

3745-509: The Roundhay Garden Scene and Leeds Bridge . In June 1878, Eadweard Muybridge created sequential series of photographs with a battery of 12 cameras along the race track at Stanford's Palo Alto Stock Farm (now the campus of Stanford University ). The shutters were automatically triggered when the wheel of a cart or the breast or legs of a horse tripped wires connected to an electromagnetic circuit. Another early pioneer

3852-530: The 1st Middlesex Militia during the War of 1812. His father, Samuel Edison Jr. moved to Vienna, Ontario , and fled to Ohio after his involvement in the Rebellion of 1837 . Edison was taught reading, writing, and arithmetic by his mother, a former school teacher. He attended school for only a few months. However, one biographer described him as a very curious child who learned most things by reading on his own. As

3959-595: The American Midwest . Early in his career he worked as a telegraph operator , which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey , where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida , in collaboration with businessmen Henry Ford and Harvey S. Firestone , and

4066-794: The Finlayson 's textile factory in Tampere, Finland in March 1882. In 1901, Edison attended the Pan-American Exposition in Buffalo, New York . His company, the Edison Manufacturing Company , was given the task of installing the electric lights on the various buildings and structures that were built for the exposition. At night Edison made a panorama photograph of the illuminated buildings. After devising

4173-535: The Thomson-Houston Electric Company of Lynn, Massachusetts (another AC-based competitor) built 22 power stations. Parallel to expanding competition between Edison and the AC companies was rising public furor over a series of deaths in the spring of 1888 caused by pole mounted high voltage alternating current lines. This turned into a media frenzy against high voltage alternating current and

4280-412: The phonograph , the motion picture camera , and early versions of the electric light bulb , have had a widespread impact on the modern industrialized world . He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory . Edison was raised in

For optical recording, the film only had a single perforation and the area where the other set of perforations would have been was exposed to a controlled bright light that would burn a waveform image that would later regulate the passage of light and playback the sound. For magnetic recording, that same area of

4494-407: The 1880s that used wax-coated cardboard cylinders. In 1876, Edison began work to improve the microphone for telephones (at that time called a "transmitter") by developing a carbon microphone , which consists of two metal plates separated by granules of carbon that would change resistance with the pressure of sound waves. A steady direct current is passed between the plates through the granules and

4601-609: The 1889 merger that formed Edison General Electric. In 1890 he told president Henry Villard he thought it was time to retire from the lighting business and moved on to an iron ore refining project that preoccupied his time. Edison's dogmatic anti-AC values were no longer controlling the company. By 1889 Edison's Electric's own subsidiaries were lobbying to add AC power transmission to their systems and in October 1890 Edison Machine Works began developing AC-based equipment. Cut-throat competition and patent battles were bleeding off cash in

4708-475: The Goldenrod plant. Edison decided on Solidago leavenworthii , also known as Leavenworth's Goldenrod. The plant, which normally grows roughly 3–4 feet tall with a 5% latex yield, was adapted by Edison through cross-breeding to produce plants twice the size and with a latex yield of 12%. During the 1911 New York Electrical show, Edison told representatives of the copper industry it was a shame he did not have

4815-574: The Lumière brothers shifted to celluloid film, which they bought from New-York's Celluloid Manufacturing Co. This they covered with their own Etiquette-bleue emulsion, had it cut into strips and perforated. In 1894, the Polish inventor Kazimierz Prószyński constructed a projector and camera in one, an invention he called the Pleograph . Due to the work of Le Prince, Friese-Greene , Edison, and

4922-523: The Lumière brothers, the movie camera had become a practical reality by the mid-1890s. The first firms were soon established for the manufacture of movie camera, including Birt Acres , Eugene Augustin Lauste , Dickson, Pathé frères, Prestwich, Newman & Guardia, de Bedts, Gaumont-Démény, Schneider, Schimpf, Akeley, Debrie, Bell & Howell, Leonard-Mitchell, Ertel, Ernemann, Eclair, Stachow, Universal, Institute, Wall, Lytax, and many others. The Aeroscope

5029-634: The US electrical business and would compete with Westinghouse for the AC market. Edison served as a figurehead on the company's board of directors for a few years before selling his shares. Edison moved from Menlo Park after the death of his first wife, Mary, in 1884, and purchased a home known as " Glenmont " in 1886 as a wedding gift for his second wife, Mina , in Llewellyn Park in West Orange, New Jersey . In 1885, Thomas Edison bought 13 acres of property in Fort Myers , Florida, for roughly $ 2,750 (equivalent to $ 93,256 in 2023) and built what

5136-629: The above mechanism to a minimum removing much of the shortcomings. The standardized frame rate for commercial sound film is 24 frames per second. The standard commercial (i.e., movie-theater film) width is 35 millimeters, while many other film formats exist. The standard aspect ratios are 1.66, 1.85, and 2.39 ( anamorphic ). NTSC video (common in North America and Japan) plays at 29.97 frame/s; PAL (common in most other countries) plays at 25 frames. These two television and video systems also have different resolutions and color encodings. Many of

5243-535: The advent of digital cameras, synchronization became a redundant term, as both visual and audio is simultaneously captured electronically. Movie cameras were available before World War II often using the 9.5 mm film format or 16 mm format. The use of movie cameras had an upsurge in popularity in the immediate post-war period giving rise to the creation of home movies. Compared to the pre-war models, these cameras were small, light, fairly sophisticated and affordable. An extremely compact 35 mm movie camera Kinamo

5350-617: The air and for military purposes . The first all-metal cine camera was the Bell & Howell Standard of 1911-12. One of the most complicated models was the Mitchell- Technicolor Beam Splitting Three-Strip Camera of 1932. With it, three colour separation originals are obtained behind a purple, a green, and a red light filter, the latter being part of one of the three different raw materials in use. In 1923, Eastman Kodak introduced

5457-424: The barium platinocyanide screens originally used by Wilhelm Röntgen , the technology was capable of producing only very faint images. The fundamental design of Edison's fluoroscope is still in use today, although Edison abandoned the project after nearly losing his own eyesight and seriously injuring his assistant, Clarence Dally . Dally made himself an enthusiastic human guinea pig for the fluoroscopy project and

5564-409: The best filament. Edison continued trying to improve this design and on November 4, 1879, filed for U.S. patent 223,898 (granted on January 27, 1880) for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires". The patent described several ways of creating the carbon filament including "cotton and linen thread, wood splints, papers coiled in various ways". It

5671-421: The camera by a clockwork mechanism to enable continuous recording over a 12- or 24-hour period. Ronalds applied his cameras to trace the ongoing variations of scientific instruments and they were used in observatories around the world for over a century. The chronophotographic gun was invented in 1882 by Étienne-Jules Marey , a French scientist and chronophotographer. It could shoot 12 images per second and

5778-423: The camera is often referred to by camera assistants as "the dumb side" because it usually lacks indicators or readouts and access to the film threading, as well as lens markings on many lens models. Later equipment often had done much to minimize these shortcomings, although access to the film movement block by both sides is precluded by basic motor and electronic design necessities. Advent of digital cameras reduced

5885-401: The close up with the success of his films. For example, one of Griffith's short films, The Lonedale Operator (1911), makes significant use of a close-up of a wrench that a character pretends is a gun. Lillian Gish remarked on Griffith's pioneering use of the close-up: The people in the front office got very upset. They came down and said: "The public doesn't pay for the head or the arms or

5992-428: The competing companies and the idea of a merger was being put forward in financial circles. The War of Currents ended in 1892 when the financier J.P. Morgan engineered a merger of Edison General Electric with its main alternating current based rival, The Thomson-Houston Company, that put the board of Thomson-Houston in charge of the new company called General Electric . General Electric now controlled three-quarters of

6099-591: The cost of interior furnishings. Edison and Mina spent many winters at their home in Fort Myers, and Edison tried to find a domestic source of natural rubber. Due to the security concerns around World War I , Edison suggested forming a science and industry committee to provide advice and research to the US military, and he headed the Naval Consulting Board in 1915. Edison became concerned with America's reliance on foreign supply of rubber and

6206-436: The critical parameters of his electric lighting system including lamp resistance by an analysis of Ohm's law , Joule's law and economics. Nearly all of Edison's patents were utility patents, which were protected for 17 years and included inventions or processes that are electrical, mechanical, or chemical in nature. About a dozen were design patents , which protect an ornamental design for up to 14 years. As in most patents,

Close-up shots do not show the subject in the broad context of its surroundings. Low-budget films may use close-ups to avoid the expense of set construction . If overused, close-ups may leave viewers uncertain as to what they are seeing. Close-ups are rarely done with wide-angle lenses because perspective causes objects closer to

6420-539: The early 1880s, AC arc lighting systems for streets and large spaces had been an expanding business in the US. With the development of transformers in Europe and by Westinghouse Electric in the US in 1885–1886, it became possible to transmit AC long distances over thinner and cheaper wires, and "step down" (reduce) the voltage at the destination for distribution to users. This allowed AC to be used in street lighting and in lighting for small business and domestic customers,

6527-667: The family moved there in 1854. He was the seventh and last child of Samuel Ogden Edison Jr. (1804–1896, born in Marshalltown, Nova Scotia ) and Nancy Matthews Elliott (1810–1871, born in Chenango County, New York ). His patrilineal family line was Dutch by way of New Jersey ; the surname had originally been "Edeson". His great-grandfather, loyalist John Edeson, fled New Jersey for Nova Scotia in 1784. The family moved to Middlesex County, Upper Canada , around 1811, and his grandfather, Capt. Samuel Edison Sr. served with

[REDACTED] Media related to Close-up shots at Wikimedia Commons Thomas Edison Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation , mass communication , sound recording , and motion pictures. These inventions, which include

6741-482: The incandescent electric lamp and was put in charge of tests and records on that device. In 1880, he was appointed chief engineer of the Edison Lamp Works. In his first year, the plant under general manager Francis Robbins Upton turned out 50,000 lamps. According to Edison, Hammer was "a pioneer of incandescent electric lighting". Frank J. Sprague , a competent mathematician and former naval officer ,

6848-408: The inventions he described were improvements over prior art . The phonograph patent, in contrast, was unprecedented in describing the first device to record and reproduce sounds. In just over a decade, Edison's Menlo Park laboratory had expanded to occupy two city blocks. Edison said he wanted the lab to have "a stock of almost every conceivable material". A newspaper article printed in 1887 reveals

6955-498: The latter preoccupation cost him his job. One night in 1867, he was working with a lead–acid battery when he spilt sulfuric acid onto the floor. It ran between the floorboards and onto his boss's desk below. The next morning Edison was fired. His first patent was for the electric vote recorder, U.S. patent 90,646 , which was granted on June 1, 1869. Finding little demand for the machine, Edison moved to New York City shortly thereafter. One of his mentors during those early years

7062-407: The lens to be unnaturally enlarged. That may convey a sense of confusion, intoxication, or another unusual mental state. There are various degrees of close-up depending on how tight (zoomed in) the shot is. The terminology varies between countries and even different companies, but in general, these are: When the close-up is used in the shooting, the subject should not be put in exactly the middle of

7169-440: The list goes on. Over his desk Edison displayed a placard with Sir Joshua Reynolds ' famous quotation: "There is no expedient to which a man will not resort to avoid the real labor of thinking." This slogan was reputedly posted at several other locations throughout the facility. In Menlo Park, Edison had created the first industrial laboratory concerned with creating knowledge and then controlling its application. Edison's name

7276-468: The market Edison's patented low voltage DC incandescent lamp system was designed to supply. Edison's DC empire suffered from one of its chief drawbacks: it was suitable only for the high density of customers found in large cities. Edison's DC plants could not deliver electricity to customers more than one mile from the plant, and left a patchwork of unsupplied customers between plants. Small cities and rural areas could not afford an Edison style system, leaving

7383-680: The members of the Vanderbilt family . Edison made the first public demonstration of his incandescent light bulb on December 31, 1879, in Menlo Park. It was during this time that he said: "We will make electricity so cheap that only the rich will burn candles." Henry Villard , president of the Oregon Railroad and Navigation Company , attended Edison's 1879 demonstration. Villard was impressed and requested Edison install his electric lighting system aboard Villard's company's new steamer,

7490-478: The moving picture. When projected at a high enough frame rate (24 frames per second or more), the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. A forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the aperture diaphragm of

7597-586: The new Eastman celluloid film, which he had perforated. A full report on the patented camera was published in the British Photographic News on February 28, 1890. He showed his cameras and film shot with them on many occasions, but never projected his films in public. He also sent details of his invention to the American inventor Thomas Edison in February 1890, which was also seen by Dickson (see below). William Kennedy Laurie Dickson ,

7704-430: The optical and mechanical elements of a movie camera are also present in the movie projector . The requirements for film tensioning, take-up, intermittent motion, loops, and rack positioning are almost identical. The camera will not have an illumination source and will maintain its film stock in a light-tight enclosure. A camera will also have exposure control via an iris aperture located on the lens . The righthand side of

7811-422: The other. It is alleged that Edison would listen to a music player or piano by clamping his teeth into the wood to absorb the sound waves into his skull. As he got older, Edison believed his hearing loss allowed him to avoid distraction and concentrate more easily on his work. Modern-day historians and medical professionals have suggested he may have had ADHD . It is known that early in his career he enrolled in

7918-423: The phonograph before the National Academy of Sciences, Congressmen, Senators and President Hayes . The Washington Post described Edison as a " genius " and his presentation as "a scene... that will live in history". Although Edison obtained a patent for the phonograph in 1878, he did little to develop it until Alexander Graham Bell , Chichester Bell , and Charles Tainter produced a phonograph-like device in

8025-426: The physics of loose-contact carbon transmitters (work that Hughes did not bother to patent). Edison used the carbon microphone concept in 1877 to create an improved telephone for Western Union . In 1886, Edison found a way to improve a Bell Telephone microphone, one that used loose-contact ground carbon, with his discovery that it worked far better if the carbon was roasted . This type was put in use in 1890 and

8132-437: The project, while Edison did all the research. Edison, however, wished to contribute $ 25,000 as well. Edison did the majority of the research and planting, sending results and sample rubber residues to his West Orange Lab. Edison employed a two-part Acid-base extraction , to derive latex from the plant material after it was dried and crushed to a powder. After testing 17,000 plant samples, he eventually found an adequate source in

8239-481: The sales of electric power systems in general. The primary reason was that Edison Electric based their design on low voltage DC, and switching a standard after they had installed over 100 systems was, in Edison's mind, out of the question. By the end of 1887, Edison Electric was losing market share to Westinghouse, who had built 68 AC-based power stations to Edison's 121 DC-based stations. To make matters worse for Edison,

8346-452: The seemingly greedy and callous lighting companies that used it. Edison took advantage of the public perception of AC as dangerous, and joined with self-styled New York anti-AC crusader Harold P. Brown in a propaganda campaign, aiding Brown in the public electrocution of animals with AC, and supported legislation to control and severely limit AC installations and voltages (to the point of making it an ineffective power delivery system) in what

8453-457: The seriousness of his claim, stating the lab contained "eight thousand kinds of chemicals, every kind of screw made, every size of needle, every kind of cord or wire, hair of humans, horses, hogs, cows, rabbits, goats, minx, camels ... silk in every texture, cocoons, various kinds of hoofs, shark's teeth, deer horns, tortoise shell ... cork, resin, varnish and oil, ostrich feathers, a peacock's tail, jet, amber, rubber, all ores ..." and

8560-595: The shoulders of the actor. They want the whole body. Let's give them their money's worth." Griffith stood very close to them and said: "Can you see my feet?" When they said no, he replied: "That's what I'm doing. I am using what the eyes can see." Close-ups are used in many ways and for many reasons. They are often employed as cutaways from a more distant shot to show detail, such as characters' emotions or some intricate activity with their hands. Close cuts to characters' faces are used far more often in television than in movies and are especially common in soap operas . For

8667-434: The signal so generated to the telephone line. Edison was one of many inventors working on the problem of creating a usable microphone for telephony by having it modulate an electric current passed through it. His work was concurrent with Emile Berliner 's loose-contact carbon transmitter (who lost a later patent case against Edison over the carbon transmitter's invention ) and David Edward Hughes ’ study and published paper on

8774-410: The single perf 16 mm film that was prestriped with a magnetic stripe. A smaller balance stripe existed between the perforations and the edge to compensate the thickness of the recording stripe to keep the film wound evenly. Double-system cameras are generally categorized as either "sync" or "non-sync." Sync cameras use crystal-controlled motors that ensure that film is advanced through the camera at

8881-509: The sprocket wheel that engaged the strip was driven by an escapement disc mechanism—the first practical system for the high-speed stop-and-go film movement that would be the foundation for the next century of cinematography . The Lumière Domitor camera, owned by brothers Auguste and Louis Lumière , was created by Charles Moisson, the chief mechanic at the Lumière works in Lyon in 1894. The camera used paper film 35 millimeters wide, but in 1895,

8988-486: The standard since the 1890s. Rather, an electronic image sensor is employed and the images are typically recorded on hard drives or flash memory —using a variety of acquisition formats . Digital SLR cameras (DSLR) designed for consumer use have also been used for some low-budget independent productions. Since the 2010s, digital movie cameras have become the dominant type of camera in the motion picture industry, being employed in film, television productions and even (to

9095-437: The technical difficulties involving film and video concern translation between the different formats. Video aspect ratios are 4:3 (1.33) for full screen and 16:9 (1.78) for widescreen. Multiple cameras may be placed side-by-side to record a single angle of a scene and repeated throughout the runtime. The film is then later projected simultaneously, either on a single three-image screen ( Cinerama ) or upon multiple screens forming

9202-503: The tools of semi professional film and news film makers. In the 1960s a new film format, Super8 , coincided with the advent of battery-operated electric movie cameras. The new film, with a larger frame print on the same width of film stock, came in a cassette that simplified changeover and developing. Another advantage of the new system is that they had the capacity to record sound, albeit of indifferent quality. Camera bodies, and sometimes lenses, were increasingly made in plastic rather than

9309-417: The varying resistance results in a modulation of the current, creating a varying electric current that reproduces the varying pressure of the sound wave. Up to that point, microphones, such as the ones developed by Johann Philipp Reis and Alexander Graham Bell , worked by generating a weak current. The carbon microphone works by modulating a direct current and, subsequently, using a transformer to transfer

9416-627: Was a fellow telegrapher and inventor named Franklin Leonard Pope , who allowed the impoverished youth to live and work in the basement of his Elizabeth, New Jersey , home, while Edison worked for Samuel Laws at the Gold Indicator Company. Pope and Edison founded their own company in October 1869, working as electrical engineers and inventors. Edison began developing a multiplex telegraphic system, which could send two messages simultaneously, in 1874. Edison's major innovation

9523-681: Was at Stratford Junction, Ontario, on the Grand Trunk Railway . He also studied qualitative analysis and conducted chemical experiments until he left the job rather than be fired after being held responsible for a near collision of two trains. Edison obtained the exclusive right to sell newspapers on the road, and, with the aid of four assistants, he set in type and printed the Grand Trunk Herald , which he sold with his other papers. This began Edison's long streak of entrepreneurial ventures, as he discovered his talents as

9630-566: Was built and patented in England in the period 1909–1911 by Polish inventor Kazimierz Prószyński . Aeroscope was the first successful hand-held operated film camera. The cameraman did not have to turn the crank to advance the film, as in all cameras of that time, so he could operate the camera with both hands, holding the camera and controlling the focus. This made it possible to film with the Aeroscope in difficult circumstances including from

9737-449: Was designed by Emanuel Goldberg for amateur and semi-professional movies in 1921. A spring motor attachment was added in 1923 to allow flexible handheld filming. The Kinamo was used by Joris Ivens and other avant-garde and documentary filmmakers in the late 1920s and early 1930s. While a basic model might have a single fixed aperture/focus lens, a better version might have three or four lenses of differing apertures and focal lengths on

9844-521: Was determined to find a native supply of rubber. Edison's work on rubber took place largely at his research laboratory in Fort Myers, which has been designated as a National Historic Chemical Landmark. The laboratory was built after Thomas Edison, Henry Ford, and Harvey S. Firestone pulled together $ 75,000 to form the Edison Botanical Research Corporation. Initially, only Ford and Firestone were to contribute funds to

9951-467: Was exposed to a poisonous dose of radiation; he later died (at the age of 39) of injuries related to the exposure, including mediastinal cancer. In 1903, a shaken Edison said: "Don't talk to me about X-rays, I am afraid of them." Nonetheless, his work was important in the development of a technology still used today. Edison invented a highly sensitive device, that he named the tasimeter , which measured infrared radiation . His impetus for its creation

10058-511: Was generally told to carry out his directions in conducting research, and he drove them hard to produce results. William Joseph Hammer , a consulting electrical engineer , started working for Edison and began his duties as a laboratory assistant in December 1879. He assisted in experiments on the telephone, phonograph, electric railway, iron ore separator , electric lighting , and other developing inventions. However, Hammer worked primarily on

10165-543: Was incorporating extreme close-ups in films such as As Seen Through a Telescope and Grandma's Reading Glass . In 1901, James Williamson , also working in Hove, made perhaps the most extreme close-up of all in The Big Swallow in which his character approaches the camera and appears to swallow it. D. W. Griffith , who pioneered screen cinematographic techniques and narrative format, is associated with popularizing

10272-634: Was later called Seminole Lodge as a winter retreat. The main house and guest house are representative of Italianate architecture and Queen Anne style architecture . The building materials were pre-cut in New England by the Kennebec Framing Company and the Stephen Nye Lumber Company of Fairfield Maine. The materials were then shipped down by boat and were constructed at a cost of $ 12,000 each, which included

10379-476: Was not until several months after the patent was granted that Edison and his team discovered that a carbonized bamboo filament could last over 1,200 hours. Attempts to prevent blackening of the bulb due to emission of charged carbon from the hot filament culminated in Edison effect bulbs, which redirected and controlled the mysterious unidirectional current. Edison's 1883 patent for voltage-regulating

10486-563: Was now being referred to as a " war of the currents ". The development of the electric chair was used in an attempt to portray AC as having a greater lethal potential than DC and smear Westinghouse, via Edison colluding with Brown and Westinghouse's chief AC rival, the Thomson-Houston Electric Company, to ensure the first electric chair was powered by a Westinghouse AC generator. Edison was becoming marginalized in his own company having lost majority control in

10593-495: Was recruited by Edward H. Johnson and joined the Edison organization in 1883. One of Sprague's contributions to the Edison Laboratory at Menlo Park was to expand Edison's mathematical methods. Despite the common belief that Edison did not use mathematics, analysis of his notebooks reveal that he was an astute user of mathematical analysis conducted by his assistants such as Francis Robbins Upton, for example, determining

10700-431: Was removed and placed back in the camera to expose the frames on the other side once the first half had been exposed. Once the film was developed it was sliced down the middle and the ends attached, giving 50-foot (15 m) of Standard 8 film from a spool of 25-foot (7.6 m) of 16 mm film. 16 mm cameras, mechanically similar to the smaller format models, were also used in home movie making but were more usually

10807-580: Was switched on, providing 110 volts direct current (DC), initially to 59 customers in lower Manhattan , quickly growing to 508 customers with 10,164 lamps. The power station was decommissioned in 1895. Eight months earlier in January 1882, to demonstrate feasibility, Edison had switched on the 93 kW first steam-generating power station at Holborn Viaduct in London. This was a smaller 110 V DC supply system, eventually supplying 3,000 street lights and

10914-498: Was the British inventor William Friese-Greene . In 1887, he began to experiment with the use of paper film, made transparent through oiling, to record motion pictures. He also said he attempted using experimental celluloid , made with the help of Alexander Parkes . In 1889, Friese-Greene took out a patent for a moving picture camera that was capable of taking up to ten photographs per second. Another model, built in 1890, used rolls of

11021-453: Was the desire to measure the heat from the solar corona during the total Solar eclipse of July 29, 1878 . The device was not patented since Edison could find no practical mass-market application for it. Motion picture camera A movie camera (also known as a film camera and cine-camera ) is a type of photographic camera that rapidly takes a sequence of photographs, either onto film stock or an image sensor , in order to produce

11128-488: Was the establishment of an industrial research lab in 1876. It was built in Menlo Park , a part of Raritan Township (now named Edison Township in his honor) in Middlesex County, New Jersey , with the funds from the sale of Edison's quadruplex telegraph . After his demonstration of the telegraph, Edison was not sure that his original plan to sell it for $ 4,000 to $ 5,000 was right, so he asked Western Union to make

11235-431: Was the first invention to capture moving images on the same chronomatographic plate using a metal shutter. In 1876, Wordsworth Donisthorpe proposed a camera to take a series of pictures on glass plates, to be printed on a roll of paper film. In 1889, he would patent a moving picture camera in which the film moved continuously. Another film camera was designed in England by Frenchman Louis Le Prince in 1888. He had built

11342-476: Was used in all telephones along with the Bell receiver until the 1980s. In 1878, Edison began working on a system of electrical illumination, something he hoped could compete with gas and oil-based lighting. He began by tackling the problem of creating a long-lasting incandescent lamp, something that would be needed for indoor use. However, Thomas Edison did not invent the light bulb. In 1840, British scientist Warren de la Rue developed an efficient light bulb using

11449-515: Was valid. To avoid a possible court battle with yet another competitor, Joseph Swan , who held an 1880 British patent on a similar incandescent electric lamp, he and Swan formed a joint company called Ediswan to manufacture and market the invention in Britain. The incandescent light bulb patented by Edison also began to gain widespread popularity in Europe as well. Mahen Theatre in Brno (in what
