98-404: Live action is a form of cinematography or videography that uses photography instead of animation . Some works combine live action with animation to create a live-action animated feature film . Live action is used to define film, video games or similar visual media. Photorealistic animation, particularly modern computer animation , is sometimes erroneously described as "live action", as in

196-406: A chronophotographic gun, which was capable of taking 12 consecutive frames a second and recording all the frames of the same picture. The late nineteenth to the early twentieth centuries brought rise to the use of film not only for entertainment purposes but for scientific exploration as well. French biologist and filmmaker Jean Painleve lobbied heavily for the use of film in the scientific field, as

294-483: A crystalline defect (edge dislocation), and incorporating a trace amount of non-silver salt as a dopant. The location, kind and number of shallow traps have a huge influence on the efficiency by which the photoelectrons create latent image centers, and consequently, on photographic sensitivity. Another important way to increase photographic sensitivity is to reduce the threshold size of developable latent images. Gold sensitization of Koslowski creates metallic gold specks on

392-417: A film stock is one of the first decisions made in preparing a typical film production. Aside from the film gauge selection – 8 mm (amateur), 16 mm (semi-professional), 35 mm (professional) and 65 mm (epic photography, rarely used except in special event venues) – the cinematographer has a selection of stocks in reversal (which, when developed, create a positive image) and negative formats along with

490-426: A films intensity, vibe, show passage of time, and have many other effects. Camera movement within a film can play a role in enhancing the visual quality and impact of a film. Some aspects of camera movement that contribute to this are: Cinematography can begin with digital image sensor or rolls of film. Advancements in film emulsion and grain structure provided a wide range of available film stocks . The selection of

588-469: A gain factor up to several billion. The development system was the most important technology that increased the photographic sensitivity in the history of photography. The action of the light on the silver halide grains within the emulsion forms sites of metallic silver in the grains. The basic mechanism by which this happens was first proposed by R. W. Gurney and N. F. Mott in 1938. The incoming photon liberates an electron , called

686-699: A great inconvenience to the scientific and medical worlds. The development of film and increased usage of cameras allowed doctors and scientists to grasp a better understanding and knowledge of their projects. The origins of today's cinema go back to the Lumière brothers , Auguste and Louis, who in 1895 developed a machine called the Cinematographe, which had the ability to capture and show moving images. The early era of cinema saw rapid innovation. Filmmakers discover and apply new methods such as editing, special effects, close-ups, etc. Hollywood began to emerge as

784-421: A latent image is a small cluster of metallic silver atoms formed in or on a silver halide crystal due to reduction of interstitial silver ions by photoelectrons (a photolytic silver cluster). If intense exposure continues, such photolytic silver clusters grow to visible sizes. This is called printing out the image. On the other hand, the formation of a visible image by the action of photographic developer

882-404: A layer just under the crystal surface where a sufficient number of edge dislocations are intentionally created, while maintaining the bulk of the crystal interior defect-free. Chemical sensitization (e.g., sulfur plus gold sensitization) is applied on the surface. As a result, the photoelectrons are concentrated to a few sensitivity sites on or very near the crystal surface, thereby greatly enhancing

980-467: A neutral one. One very important way to increase photographic sensitivity is to manipulate the electron traps in each crystal. A pure, defect-free crystal exhibits poor photographic sensitivity, since it lacks a shallow electron trap that facilitates the formation of a latent image. In such a case, many of the photoelectrons will recombine with the silver halide crystal and be wasted. Shallow electron traps are created by sulfur sensitization, introduction of

1078-602: A number of ways. Each emulsion has a place within each crystal where LIs are formed preferentially. They are called "sensitivity centers." Emulsions that form LIs in the interior are called internal(ly) sensitive emulsions, and those that form LI on the surface are called surface sensitive emulsions. The sensitivity type largely reflects the site of very shallow electron traps that form latent images effectively. Most, if not all, old technology negative film emulsions had many unintentionally created edge dislocation sites (and other crystalline defects) internally and sulfur sensitization

1176-406: A photoelectron, from a silver halide crystal. Photoelectrons migrate to a shallow electron trap site (a sensitivity site), where the electrons reduce silver ions to form a metallic silver speck. A positive hole must also be generated, but it is largely ignored. Subsequent work has slightly modified this picture, so that "hole" trapping is also considered (Mitchell, 1957). Since then, understanding of

1274-441: A railway engine were usually specifically referred to as " phantom rides ". In 1897, Robert W. Paul had the first real rotating camera head made to put on a tripod, so that he could follow the passing processions of Queen Victoria's Diamond Jubilee in one uninterrupted shot. This device had the camera mounted on a vertical axis that could be rotated by a worm gear driven by turning a crank handle, and Paul put it on general sale

1372-416: A relevant and widely used technique in modern filmmaking. It continues to be employed by filmmakers to evoke specific moods, convey a sense of timelessness, and enhance the artistic expression of their stories. There are many types of Cinematography that each differ based on production purpose and process. These different types of Cinematography are similar in the sense that they all have the goal of conveying

1470-563: A specific emotion, mood or feeling. For each different style however they can often convey different emotions and purposes. Some examples of different types of Cinematography can be known as Realism. This style of cinematography aims to create a realistic portrayal of the world, often using natural lighting, handheld cameras, and a documentary-like approach to filming. Classic Hollywood is a style of cinematography characterized by its use of highly polished, studio-produced films with glamorous sets, bright lighting, and romanticized narratives. Film Noir

1568-409: A sped-up effect is shown. Time lapses are used most effectively to show things like sunrises, natural movement, or growth. They are commonly used to show passage of time in a shorter sequence. Reverse motion is filming a scene normally, then playing the film in reverse. This is usually used to create uncommon/surreal effects, and create unusual scenes. The various techniques involving speed all can add to

1666-417: A stable latent image center, a smaller and less stable silver speck is made. Further generation of photoelectrons is necessary to grow this speck to a larger, stable, latent image. There is a finite probability that this intermediate unstable speck will decompose before next available photoelectrons can stabilize it. This probability increases with decreasing irradiance level. LIRF can be improved by optimizing

1764-488: A timeless and classic feel. By stripping away color, filmmakers can emphasize the composition, shapes, and textures within the frame, enhancing the visual impact. Notable films that have employed black-and-white cinematography include classics such as Casablanca (1942), Raging Bull (1980), and Schindler's List (1993). These films showcase the power and versatility of black-and-white cinematography in creating emotionally resonant visuals. Black-and-white cinematography remains

1862-520: A track parallel to the horse's, and each camera shutter was controlled by a trip wire triggered by the horse's hooves. They were 21 inches apart to cover the 20 feet taken by the horse stride, taking pictures at one-thousandth of a second. At the end of the decade, Muybridge had adapted sequences of his photographs to a zoopraxiscope for short, primitive projected "movies", which were sensations on his lecture tours by 1879 or 1880. Four years later, in 1882, French scientist Étienne-Jules Marey invented

1960-582: A transparent celluloid strip 35 mm wide. The results of this work were first shown in public in 1893, using the viewing apparatus also designed by Dickson, the Kinetoscope . Contained within a large box, only one person at a time looking into it through a peephole could view the movie. In the following year, Charles Francis Jenkins and his projector, the Phantoscope , made a successful audience viewing while Louis and Auguste Lumière perfected

2058-537: A very brief but intense laser. Problems due to HIRF were the major technical challenge in development of such products. Color photographic papers are usually made with very high percentage of silver chloride (about 99%) and the rest is bromide and/or iodide. Chloride emulsions have particularly poor HIRF and usually suffer from LIRF. Paper manufacturers use dopants and precise control of the dislocation sites to improve (to virtually eliminate) HIRF for this new application. Low-intensity reciprocity failure (LIRF) occurs when

2156-419: A wide range of film speeds (varying sensitivity to light) from ISO 50 (slow, least sensitive to light) to 800 (very fast, extremely sensitive to light) and differing response to color (low saturation , high saturation) and contrast (varying levels between pure black (no exposure) and pure white (complete overexposure). Advancements and adjustments to nearly all gauges of film create the "super" formats wherein

2254-417: A wider lens can give key information that takes place in the background of a shot. Camera distance can highlight specific details that can be important to a film shot. From very far away, a group of people can all look the same, but once you zoom in very close, the viewer is able to see differences within the population through details like facial expression and body language. Coloring is similar to lighting, in

2352-452: A yellow filter, which cuts down on blue wavelengths of light, can be used to darken a daylight sky (by eliminating blue light from hitting the film, thus greatly underexposing the mostly blue sky) while not biasing most human flesh tone. Filters can be used in front of the lens or, in some cases, behind the lens for different effects. Certain cinematographers, such as Christopher Doyle , are well known for their innovative use of filters; Doyle

2450-415: Is a limit in increasing the photographic speed of the system by boosting the developer potential; if the solution's reduction potential is set high enough to exploit smaller silver cluster, at some point the solution begins to reduce silver halide crystals regardless of exposure. This is called fog , which is metallic silver made from non-imagewise (exposure-nonspecific) reduction of silver halide crystals. It

2548-402: Is a style of cinematography that is characterized by its use of stark contrast and chiaroscuro lighting, low-key lighting, and a dark, brooding atmosphere. It often features crime, mystery, and morally ambiguous characters. To convey mood, emotion, narrative and other factors within the shot, cinematography is implemented by using different aspects within a film. Lighting on the scene can affect

2646-416: Is a technique used in filmmaking where the images are captured and presented in shades of gray, without color. This artistic approach has a rich history and has been employed in various films throughout cinema's evolution. It is a powerful tool that allows filmmakers to emphasize contrast, texture, and lighting, enhancing the visual storytelling experience. The use of black-and-white cinematography dates back to

2744-419: Is a vital element in cinematography that can be used in a variety of ways, such as the creation of action, or a sense of movement. Speed can be further used to slow down time, highlight important moments, and often times build a sense of suspense in a film. Slow motion is a technique which involves filming at a higher frame rate, then playing the footage again at a normal speed. This creates a slowed-down effect in

2842-438: Is called fogging developer and such a solution is used in the second developer of reversal processing.) This conversion is due to electrochemical reduction, wherein the latent image centers act as a catalyst. A developer solution must have a reduction potential that is strong enough to develop sufficiently exposed silver halide crystals having a latent image center. At the same time, developer must have reduction potential that

2940-400: Is called developing out the image. The size of a silver cluster in the latent image can be as small as a few silver atoms. However, in order to act as an effective latent image center, at least four silver atoms are necessary. On the other hand, a developed silver grain can have billions of silver atoms. Therefore, photographic developer acting on the latent image is a chemical amplifier with

3038-479: Is common when the crystal is exposed by intense but brief light, such as flash tube. This reduces photographic speed and contrast. This is common with emulsions optimized for highest sensitivity with long exposure using old emulsion technology. HIRF is due to creation of many latent subimages that are not developable due to small size. Because of brief and intense exposure, many photoelectrons are created simultaneously. They make many latent subimages (that cannot render

3136-410: Is determined by the aperture size and the focal distance. A large or deep depth of field is generated with a very small iris aperture and focusing on a point in the distance, whereas a shallow depth of field will be achieved with a large (open) iris aperture and focusing closer to the lens. Depth of field is also governed by the format size. If one considers the field of view and angle of view, the smaller

3234-440: Is often a translucent color medium pressed between two planes of optical glass. Color filters work by blocking out certain color wavelengths of light from reaching the film. With color film, this works very intuitively wherein a blue filter will cut down on the passage of red, orange, and yellow light and create a blue tint on the film. In black-and-white photography, color filters are used somewhat counter-intuitively; for instance,

3332-420: Is one of the chief benefits. The focal length of the lens determines the angle of view and, therefore, the field of view . Cinematographers can choose from a range of wide-angle lenses , "normal" lenses and long focus lenses , as well as macro lenses and other special effect lens systems such as borescope lenses. Wide-angle lenses have short focal lengths and make spatial distances more obvious. A person in

3430-428: Is still used by some directors, especially in specific applications or out of fondness for the format. From its birth in the 1880s, movies were predominantly monochrome. Contrary to popular belief, monochrome does not always mean black-and-white; it means a movie shot in a single tone or color. Since the cost of tinted film bases was substantially higher, most movies were produced in black-and-white monochrome. Even with

3528-495: Is the art of motion picture (and more recently, electronic video camera ) photography. Cinematographers use a lens to focus reflected light from objects into a real image that is transferred to some image sensor or light-sensitive material inside the movie camera . These exposures are created sequentially and preserved for later processing and viewing as a motion picture. Capturing images with an electronic image sensor produces an electrical charge for each pixel in

3626-523: Is the earliest surviving motion picture. This movie was shot on paper film. An experimental film camera was developed by British inventor William Friese Greene and patented in 1889. W. K. L. Dickson , working under the direction of Thomas Alva Edison , was the first to design a successful apparatus, the Kinetograph , patented in 1891. This camera took a series of instantaneous photographs on standard Eastman Kodak photographic emulsion coated onto

3724-431: Is the hand-tinted Annabelle Serpentine Dance in 1895 by Edison Manufacturing Company . Machine-based tinting later became popular. Tinting continued until the advent of natural color cinematography in the 1910s. Many black-and-white movies have been colorized recently using digital tinting. This includes footage shot from both world wars, sporting events and political propaganda. In 1902, Edward Raymond Turner produced

3822-502: Is weak enough not to reduce unexposed silver halide crystals. In a suitably formulated developer, electrons are injected to the silver halide crystals only through silver speck (latent image). Therefore, it is very important for the chemical reduction potential of the developer solution (not the standard reduction potential of the developing agent) to be somewhere higher than the Fermi energy level of small metallic silver clusters (that is,

3920-683: The Cinématographe , an apparatus that took, printed, and projected film, in Paris in December 1895. The Lumière brothers were the first to present projected, moving, photographic, pictures to a paying audience of more than one person. In 1896, movie theaters were open in France (Paris, Lyon , Bordeaux , Nice, Marseille ); Italy ( Rome , Milan, Naples , Genoa , Venice, Bologna , Forlì ); Brussels ; and London. The chronological improvements in

4018-580: The film laboratory to process the film stock can also offer a considerable variance in the image produced. By controlling the temperature and varying the duration in which the film is soaked in the development chemicals, and by skipping certain chemical processes (or partially skipping all of them), cinematographers can achieve very different looks from a single film stock in the laboratory. Some techniques that can be used are push processing , bleach bypass , and cross processing . Most of modern cinema uses digital cinematography and has no film stocks , but

4116-473: The "real" actors, such as Michael Jordan , Bob Hoskins and Julie Andrews , as opposed to the animated "actors", such as Roger and Jessica Rabbit . As use of computer-generated imagery (CGI) in films has become a major trend, some critics, such as Mark Langer, have discussed the relationship between live action and animation. New films that use computer-generated special-effects can not be compared to live-action films using cartoon characters because of

4214-689: The 1830s, three different solutions for moving images were invented based on the concept of revolving drums and disks, the stroboscope by Simon von Stampfer in Austria, the phenakistoscope by Joseph Plateau in Belgium, and the zoetrope by William Horner in Britain. In 1845, Francis Ronalds invented the first successful camera able to make continuous recordings of the varying indications of meteorological and geomagnetic instruments over time. The cameras were supplied to numerous observatories around

4312-469: The 2010s, digital cinematography has become the dominant form of cinematography after largely superseding film cinematography. Numerous aspects contribute to the art of cinematography, including: The first film cameras were fastened directly to the head of a tripod or other support, with only the crudest kind of leveling devices provided, in the manner of the still-camera tripod heads of the period. The earliest film cameras were thus effectively fixed during

4410-445: The advent of early color experiments, the greater expense of color meant films were mostly made in black-and-white until the 1950s, when cheaper color processes were introduced, and in some years percentage of films shot on color film surpassed 51%. By the 1960s, color became by far the dominant film stock. In the coming decades, the usage of color film greatly increased while monochrome films became scarce. Black-and-white cinematography

4508-416: The area of the film used to capture a single frame of an image is expanded, although the physical gauge of the film remains the same. Super 8 mm , Super 16 mm, and Super 35  mm all utilize more of the overall film area for the image than their "regular" non-super counterparts. The larger the film gauge, the higher the overall image resolution clarity and technical quality. The techniques used by

4606-416: The artistic choices and technical considerations involved in creating compelling black-and-white imagery, offering a comprehensive understanding of the technique. Black-and-white cinematography allows filmmakers to focus on the interplay of light and shadow, emphasizing the contrast between different elements within a scene. This technique can evoke a sense of nostalgia, evoke a specific time period, or create

4704-413: The camera's sensor designers perceptions of various film stocks and image adjustment parameters. Filters , such as diffusion filters or color effect filters, are also widely used to enhance mood or dramatic effects. Most photographic filters are made up of two pieces of optical glass glued together with some form of image or light manipulation material between the glass. In the case of color filters, there

4802-473: The camera. By the late 1920s, most of the movies produced were sound films. Wide screen formats were first experimented within the 1950s. By the 1970s, most movies were color films. IMAX and other 70mm formats gained popularity. Wide distribution of films became commonplace, setting the ground for "blockbusters." Film cinematography dominated the motion picture industry from its inception until the 2010s when digital cinematography became dominant. Film cinematography

4900-454: The cameras themselves can be adjusted in ways that go far beyond the abilities of one particular film stock. They can provide varying degrees of color sensitivity, image contrast, light sensitivity and so on. One camera can achieve all the various looks of different emulsions. Digital image adjustments such as ISO and contrast are executed by estimating the same adjustments that would take place if actual film were in use, and are thus vulnerable to

4998-581: The case of some media reports about Disney's remake of the traditionally animated The Lion King from 1994. According to the Cambridge English Dictionary , live action involves "real people or animals, not models, or images that are drawn, or produced by computer". As the normal process of making visual media involves live action, the term itself is usually superfluous. However, it makes an important distinction in situations in which one might normally expect animation, such as when

5096-399: The crystal developable), rather than one or a few latent images (that can). HIRF can be improved by incorporating dopants that create temporary deep electron traps, optimizing the degree of sulfur sensitization, introducing crystalline defects (edge dislocation). In recent years, many photographic prints are made by scanning laser exposure. Each location on a photographic paper is exposed by

5194-403: The crystal is exposed with weak light of long duration, such as in astronomical photography. LIRF is due to inefficiency of forming a latent image, and this reduces photographic speed but increases contrast. Due to low level of exposure irradiance (intensity), a single crystal may have to wait for a significant amount of time between absorbing sufficient number of photons. In the process of making

5292-446: The crystal is used to decrease the threshold size of metallic silver cluster that can render the crystal developable. For further discussion, refer to Tani 1995 and Hamilton 1988. Under normal conditions the latent image, which may be as small as a few atoms of metallic silver on each halide grain, is stable for many months. Subsequent development can then reveal a visible metallic image. A famous instance of latent-image stability are

5390-411: The crystal surface, which by itself does not render the crystal developable. When a latent image is formed around the gold speck, the presence of gold is known to reduce the number of metallic silver atoms necessary to render the crystal developable. Another important concept in increasing photographic sensitivity is to separate photoholes away from photoelectrons and sensitivity sites. This should reduce

5488-533: The distance is shown as much smaller while someone in the front will loom large. On the other hand, long focus lenses reduce such exaggerations, depicting far-off objects as seemingly close together and flattening perspective. The differences between the perspective rendering is actually not due to the focal length by itself, but by the distance between the subjects and the camera. Therefore, the use of different focal lengths in combination with different camera to subject distances creates these different rendering. Changing

5586-498: The earliest digitally shot feature movies, Julia and Julia (1987). In 1998, with the introduction of HDCAM recorders and 1920×1080 pixel digital professional video cameras based on CCD technology, the idea, now re-branded as "digital cinematography", began to gain traction. Shot and released in 1998, The Last Broadcast is believed by some to be the first feature-length video shot and edited entirely on consumer-level digital equipment. In May 1999, George Lucas challenged

5684-416: The early days of cinema when color film was not yet available. Filmmakers relied on this technique to create visually striking and atmospheric films. Even with the advent of color film technology, black-and-white cinematography continued to be utilized for artistic and thematic purposes. Ken Dancyger's book The Technique of Film and Video Editing: History, Theory, and Practice provides valuable insights into

5782-640: The efficiency with which the latent image is produced. Emulsions with different structures were made for other applications, such as direct positive emulsions. Direct positive emulsion has fog centers built into the core of the emulsion, which is bleached by photoholes generated upon exposure. This type of emulsion produces a positive image upon development in a conventional developer, without reversal processing. A developer solution converts silver halide crystals to metallic silver grains, but it acts only on those having latent image centers. (A solution that converts all silver halide crystals to metallic silver grains

5880-466: The film, which can put emphasis on or add fluidity to a scene. On the other hand, fast motion is the opposite of slow motion, filming at a lower frame rate and then playing the film back at a normal speed. This creates a sped-up effect which can help to emphasize passage of time, or create a sense of urgency. Time lapse is when you take a series of still photographs at a regular interval over a long period of time. From here, if you play them back continuously,

5978-537: The film-like qualities of their images. More recently, more and more dedicated video cameras are being equipped with larger sensors capable of 35mm film-like depth of field. The aspect ratio of an image is the ratio of its width to its height. This can be expressed either as a ratio of 2 integers, such as 4:3, or in a decimal format, such as 1.33:1 or simply 1.33. Different ratios provide different aesthetic effects. Standards for aspect ratio have varied significantly over time. Latent image In more physical terms,

6076-458: The first films with a natural color process rather than using colorization techniques. In 1909, Kinemacolor was first shown to the public. In 1917, the earliest version of Technicolor was introduced. Kodachrome was introduced in 1935. Eastmancolor was introduced in 1950 and became the color standard for the rest of the century. In the 2010s, color films were largely superseded by color digital cinematography. In digital cinematography,

6174-514: The focal length only while keeping the same camera position does not affect perspective but the camera angle of view only. A zoom lens allows a camera operator to change his focal length within a shot or quickly between setups for shots. As prime lenses offer greater optical quality and are "faster" (larger aperture openings, usable in less light) than zoom lenses, they are often employed in professional cinematography over zoom lenses. Certain scenes or even types of filmmaking, however, may require

6272-462: The foreground and background of the sets in sharp focus. This practice is known as deep focus . Deep focus became a popular cinematographic device from the 1940s onward in Hollywood. Today, the trend is for more shallow focus . To change the plane of focus from one object or character to another within a shot is commonly known as a rack focus . Early in the transition to digital cinematography,

6370-468: The historical and theoretical aspects of black-and-white cinematography. Dancyger explores how this technique has been employed throughout film history, examining its impact on storytelling, mood, and visual aesthetics. The book delves into the artistic choices and technical considerations involved in creating compelling black-and-white imagery, offering a comprehensive understanding of the technique. Black-and-white cinematography allows filmmakers to focus on

6468-535: The image is, the shorter the focal length should be, as to keep the same field of view. Then, the smaller the image is, the more depth of field is obtained, for the same field of view. Therefore, 70mm has less depth of field than 35mm for a given field of view, 16mm more than 35mm, and early video cameras, as well as most modern consumer level video cameras, even more depth of field than 16mm. In Citizen Kane (1941), cinematographer Gregg Toland and director Orson Welles used tighter apertures to create every detail of

6566-506: The image, which is electronically processed and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible latent images on the film stock, which are chemically " developed " into a visible image . The images on the film stock are projected for viewing in the same motion picture. Cinematography finds uses in many fields of science and business, as well as for entertainment purposes and mass communication . In

6664-417: The images are captured and presented in shades of gray, without color. This artistic approach has a rich history and has been employed in various films throughout cinema's evolution. It is a powerful tool that allows filmmakers to emphasize contrast, texture, and lighting, enhancing the visual storytelling experience. The use of black-and-white cinematography dates back to the early days of cinema when color film

6762-450: The inability of digital video cameras to easily achieve shallow depth of field, due to their small image sensors, was initially an issue of frustration for film makers trying to emulate the look of 35mm film. Optical adapters were devised which accomplished this by mounting a larger format lens which projected its image, at the size of the larger format, on a ground glass screen preserving the depth of field. The adapter and lens then mounted on

6860-537: The interplay of light and shadow, emphasizing the contrast between different elements within a scene. This technique can evoke a sense of nostalgia, evoke a specific time period, or create a timeless and classic feel. By stripping away color, filmmakers can emphasize the composition, shapes, and textures within the frame, enhancing the visual impact. Notable films that have employed black-and-white cinematography include classics such as Casablanca (1942), Raging Bull (1980), and Schindler's List (1993). These films showcase

6958-538: The late 1970s to early 1980s, the entertainment industry slowly began transitioning to digital imaging and digital video over the next two decades. The CCD was followed by the CMOS active-pixel sensor ( CMOS sensor ), developed in the 1990s. Beginning in the late 1980s, Sony began marketing the concept of " electronic cinematography", utilizing its analog Sony HDVS professional video cameras . The effort met with very little success. However, this led to one of

7056-427: The latent image) but well below the conduction band of unexposed silver halide crystals. Generally, weakly exposed crystals have smaller silver clusters. Silver clusters of smaller sizes have a higher Fermi level, and therefore more crystals are developed as the developer's reduction potential is increased. However, again, the developer potential must be well below the conduction band of silver halide crystal. Thus there

7154-610: The mecca of the film industry, and many of the famous studios today such as Warner Bros and Paramount Pictures began to rule the film world. Over time, cinema and cinematography have changed drastically. From the silent films of the early 20th century, to the ability of sound to be added to films in the 1920s, widescreen and color films in the 50s, huge improvements in general creativity and methodology have emerged. The experimental film Roundhay Garden Scene , filmed by Louis Le Prince in Roundhay , Leeds , England, on October 14, 1888,

7252-400: The mechanism of sensitivity and latent image formation has been greatly improved. A latent image is formed when light changes the charge atoms in the molecule. Taking bromine as a halide for this example, when light hits a silver halide molecule, the halide is changed from a negative charge to a neutral one, releasing an electron that then changes the charge of the silver from a positive one to

7350-493: The medium may be listed concisely. In 1896, Edison showed his improved Vitascope projector, the first commercially successful projector in the U.S. Cooper Hewitt invented mercury lamps which made it practical to shoot films indoors without sunlight in 1905. The first animated cartoon was produced in 1906. Credits began to appear at the beginning of motion pictures in 1911. The Bell and Howell 2709 movie camera invented in 1915 allowed directors to make close-ups without physically moving

7448-485: The mood of a scene or film. Darker shots with less natural light can be gloomy, scary, sad, intense. Brighter lighting can equate to a happier, exciting, more positive mood. Camera angle can affect a scene by setting perspective. It conveys how characters or the audience see something, and through what angle. Camera angle can also play an important role by highlighting either a close up detail, or background setting. A close up angle can highlight detail on someone's face, while

7546-404: The movie is shot on digital media such as flash storage , as well as distributed through a digital medium such as a hard drive . The basis for digital cameras are metal–oxide–semiconductor (MOS) image sensors . The first practical semiconductor image sensor was the charge-coupled device (CCD), based on MOS capacitor technology. Following the commercialization of CCD sensors during

7644-519: The new medium was more efficient in capturing and documenting the behavior, movement, and environment of microorganisms, cells, and bacteria, than the naked eye. The introduction of film into scientific fields allowed for not only the viewing of "new images and objects, such as cells and natural objects, but also the viewing of them in real time", whereas prior to the invention of moving pictures, scientists and doctors alike had to rely on hand-drawn sketches of human anatomy and its microorganisms. This posed

7742-449: The next year. Shots taken using such a "panning" head were also referred to as "panoramas" in the film catalogues of the first decade of the cinema. This eventually led to the creation of a panoramic photo as well. The standard pattern for early film studios was provided by the studio which Georges Méliès had built in 1897. This had a glass roof and three glass walls constructed after the model of large studios for still photography, and it

7840-658: The perceived realism of both styles combined. In producing a movie, both live action and animation have their own pros and cons. Unlike animation, live action involves the photography of actors and actresses, as well as sets and props making the movie seem personal and as close to reality as possible. The only drawback is one's budget. On the other hand, animation works well in conveying abstract ideas but it generally takes much longer to produce. Cinematography Cinematography (from Ancient Greek κίνημα ( kínēma )  'movement' and γράφειν ( gráphein )  'to write, draw, paint, etc.')

7938-421: The power and versatility of black-and-white cinematography in creating emotionally resonant visuals. Black-and-white cinematography remains a relevant and widely used technique in modern filmmaking. It continues to be employed by filmmakers to evoke specific moods, convey a sense of timelessness, and enhance the artistic expression of their stories. After the advent of motion pictures, a tremendous amount of energy

8036-427: The probability of recombination. Reduction sensitization is one possible implementation of this concept. The recent 2-electron sensitization technique is built on this concept. However, the scientific understanding of the behavior of photoholes is more limited than that of photoelectrons. On the other hand, a deep electron trap or a site that facilitates recombination will compete for photoelectrons and therefore reduces

8134-504: The sensitivity. However, these manipulations are used, for example, to enhance contrast of the emulsion. Reciprocity law failure is a phenomenon where the same amount of exposure (irradiance multiplied by duration of exposure) produces different image density when the irradiance (and thus duration) is varied. There are two kinds of reciprocity failure. They are both related to poor efficiency of utilizing photoelectrons to create latent image centers. High-intensity reciprocity failure (HIRF)

8232-441: The shot, and hence the first camera movements were the result of mounting a camera on a moving vehicle. The first known of these was a film shot by a Lumière cameraman from the back platform of a train leaving Jerusalem in 1896, and by 1898, there were a number of films shot from moving trains. Although listed under the general heading of "panoramas" in the sales catalogues of the time, those films shot straight forward from in front of

8330-408: The small format video camera which in turn focused on the ground glass screen. Digital SLR still cameras have sensor sizes similar to that of the 35mm film frame, and thus are able to produce images with similar depth of field. The advent of video functions in these cameras sparked a revolution in digital cinematography, with more and more film makers adopting still cameras for the purpose because of

8428-461: The stability of latent subimage, optimizing sulfur sensitization, and introduction of crystalline defects (edge dislocation). Depending on the silver halide crystal, the latent image may be formed inside or outside of the crystal. Depending on where the LI is formed, the photographic properties and the response to developer vary. Current emulsion technology allows very precise manipulation of this factor in

8526-615: The supremacy of the movie-making medium of film for the first time by including footage filmed with high-definition digital cameras in Star Wars: Episode I – The Phantom Menace . In late 2013, Paramount became the first major studio to distribute movies to theaters in digital format, eliminating 35mm film entirely. Since then the demand of movies to be developed onto digital format rather than 35mm has increased significantly. As digital technology improved, movie studios began increasingly shifting toward digital cinematography. Since

8624-420: The use of zooms for speed or ease of use, as well as shots involving a zoom move. As in other photography, the control of the exposed image is done in the lens with the control of the diaphragm aperture . For proper selection, the cinematographer needs that all lenses be engraved with T-stop , not f-stop so that the eventual light loss due to the glass does not affect the exposure control when setting it using

8722-426: The usual meters. The choice of the aperture also affects image quality (aberrations) and depth of field. Focal length and diaphragm aperture affect the depth of field of a scene – that is, how much the background, mid-ground and foreground will be rendered in "acceptable focus" (only one exact plane of the image is in precise focus) on the film or video target. Depth of field (not to be confused with depth of focus )

8820-404: The way that it plays an important role in setting mood and emotion throughout a shot. A color like green can convey balance and peace through scenes of nature. A shot with a lot of red can express anger, intensity, passion or love. While some of these emotions might not come out intentionally while seeing color, it is a subconscious fact that color within cinematography can have a large effect. Speed

8918-455: The work is adapted from a video game , or from an animated cartoon . The phrase "live action" also occurs within an animation context to refer to non-animated characters: in a live-action/animated film such as Space Jam , Who Framed Roger Rabbit , Looney Tunes: Back in Action , or Mary Poppins in which humans and cartoons co-exist. In this case, the "live-action" characters are

9016-450: The world and some remained in use until well into the 20th century. William Lincoln patented a device, in 1867 that showed animated pictures called the "wheel of life" or " zoopraxiscope ". In it moving drawings or photographs were watched through a slit. On 19 June 1878, Eadweard Muybridge successfully photographed a horse named " Sallie Gardner " in fast motion using a series of 24 stereoscopic cameras. The cameras were arranged along

9114-442: Was a pioneer for increased usage of filters in movies and is highly respected throughout the cinema world. Lenses can be attached to the camera to give a certain look, feel, or effect by focus, color, etc. As does the human eye , the camera creates perspective and spatial relations with the rest of the world. However, unlike one's eye, a cinematographer can select different lenses for different purposes. Variation in focal length

9212-433: Was also found that, when developer solution is optimally formulated, the maximum photographic speed is rather insensitive to the choice of developing agent (James 1945), and there exists a limit for the size of silver cluster that can be developed. One way to improve this problem is the use of the gold sensitization technique of Koslowski. A small metallic gold cluster whose Fermi level is high enough to prevent development of

9310-407: Was fitted with thin cotton cloths that could be stretched below the roof to diffuse the direct ray of the sun on sunny days. The soft overall light without real shadows that this arrangement produced, which also exists naturally on lightly overcast days, was to become the basis for film lighting in film studios for the next decade. Black-and-white cinematography is a technique used in filmmaking where

9408-507: Was invested in the production of photography in natural color. The invention of the talking picture further increased the demand for the use of color photography. However, in comparison to other technological advances of the time, the arrival of color photography was a relatively slow process. Early movies were not actually color movies since they were shot monochrome and hand-colored or machine-colored afterward (such movies are referred to as colored and not color ). The earliest such example

9506-615: Was not yet available. Filmmakers relied on this technique to create visually striking and atmospheric films. Even with the advent of color film technology, black-and-white cinematography continued to be utilized for artistic and thematic purposes. Ken Dancyger's book The Technique of Film and Video Editing: History, Theory, and Practice provides valuable insights into the historical and theoretical aspects of black-and-white cinematography. Dancyger explores how this technique has been employed throughout film history, examining its impact on storytelling, mood, and visual aesthetics. The book delves into

9604-468: Was performed on the surface of the crystal. Because multiple sensitivity centers are present, the emulsion had both internal and surface sensitivity. That is, photoelectrons may migrate to one of many sensitivity centers. In order to exploit the maximum sensitivity of such emulsions, it is generally considered that the developer must have some silver halide solvent action to make the internal latent image sites accessible. Many modern negative emulsions introduce
