Cinematography () is the art of motion picture (and more recently, electronic video camera) photography.
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 the image, which is Video processing and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible on the film stock, which are chemically "developed" into a visible image. The images on the film stock are Movie projector 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 1845, Francis Ronalds invented the first successful camera able to make continuous recordings of the varying indications of meteorology and geomagnetic instruments over time. The cameras were supplied to numerous observatories around 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 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 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 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 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. In the early-to-mid-20th Century, filmmakers discovered and applied new methods such as editing, special effects, close-ups, sound, widescreen, color films, and more. Hollywood began to emerge as the Mecca of the film industry, and many of the famous studios from that time still exist over 100 years later in the early-mid 21st Century.
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,
In the following year, Charles Francis Jenkins and his projector, the Phantoscope, made a successful audience viewing while Louis and Auguste Lumière perfected 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 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 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 is still used by some directors, especially in specific applications or out of fondness for the format.
Black-and-white cinematography is a technique used 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 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 early 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 insights into the historical and theoretical aspects of black-and-white cinematography. Dancyger explores how this technique has been employed, 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 an 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 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 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.
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 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 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.
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 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 "electronics cinematography", utilizing its analog Sony HDVS professional video cameras. The effort met with very little success. However, this led to one of 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 the supremacy of the movie-making medium of film for the first time by including footage filmed with high-definition digital cameras in . 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 the 2010s, digital cinematography has become the dominant form of cinematography after largely superseding film cinematography.
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 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 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.

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 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 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.
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 film (which, when developed, create a positive image) and negative formats along with a wide range of (varying sensitivity to light) from Film speed 50 (slow, least sensitive to light) to 800 (very fast, extremely sensitive to light) and differing response to color (low Colorfulness, 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 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 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 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 the camera's sensor designers perceptions of various film stocks and image adjustment parameters.
Certain cinematographers, such as Christopher Doyle, are well known for their innovative use of filters; Doyle was a pioneer for increased usage of filters in movies and is highly respected throughout the cinema world.
A zoom lens allows a camera operator to change his focal length within a shot or quickly between setups for shots. As 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 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-number so that the eventual light loss due to the glass does not affect the exposure control when setting it using the usual meters. The choice of the aperture also affects image quality (aberrations) and depth of field.
In Citizen Kane (1941), cinematographer Gregg Toland and director Orson Welles used tighter apertures to create every detail of 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, 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 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 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.
During the silent era, aspect ratios varied widely, from square , all the way up to the extreme widescreen 4:1 Polyvision. However, from the 1910s, silent motion pictures generally settled on the ratio of 4:3 (1.33). The introduction of sound-on-film briefly narrowed the aspect ratio, to allow room for a sound stripe. In 1932, a new standard was introduced, the Academy ratio of 1.37, by means of thickening the frame line.
For years, mainstream cinematographers were limited to using the academy ratio, but in the 1950s, thanks to the popularity of Cinerama, widescreen ratios were introduced in an effort to pull audiences back into the theater and away from their home television sets. These new widescreen formats provided cinematographers a wider frame within which to compose their images.
Many different proprietary photographic systems were invented and used in the 1950s to create widescreen movies, but one dominated film: the anamorphic process, which optically squeezes the image to photograph twice the horizontal area to the same size vertical as standard "spherical" lenses. The first commonly used anamorphic format was CinemaScope, which used a 2.35 aspect ratio, although it was originally 2.55. CinemaScope was used from 1953 to 1967, but due to technical flaws in the design and its ownership by Fox, several third-party companies, led by Panavision's technical improvements in the 1950s, dominated the anamorphic cine lens market. Changes to SMPTE projection standards altered the projected ratio from 2.35 to 2.39 in 1970, although this did not change anything regarding the photographic anamorphic standards; all changes in respect to the aspect ratio of anamorphic 35 mm photography are specific to camera or projector gate sizes, not the optical system. After the "widescreen wars" of the 1950s, the motion-picture industry settled into 1.85 as a standard for theatrical projection in the United States and the United Kingdom. This is a cropped version of 1.37. Europe and Asia opted for 1.66 at first, although 1.85 has largely permeated these markets in recent decades. Certain "epic" or adventure movies utilized the anamorphic 2.39 (often incorrectly denoted '2.40')
In the 1990s, with the advent of high-definition video, television engineers created the 1.78 (16:9) ratio as a mathematical compromise between the theatrical standard of 1.85 and television's 1.33, as it was not practical to produce a traditional CRT television tube with a width of 1.85. Until that change, nothing had ever been originated in 1.78. Today, this is a standard for high-definition video and for widescreen television.
Importance of Lighting in Film Lighting in film is essential for three primary reasons: visibility, composition, and mood. Firstly, lighting ensures that the subject or scene is properly illuminated, allowing viewers to perceive the details and understand the narrative. It helps in guiding the audience's attention to specific elements within the frame, highlighting important characters or objects. Secondly, lighting contributes to the composition of a shot. Filmmakers strategically place lights to create balance, depth, and visual interest within the frame. It allows them to control the visual elements within the scene, emphasizing certain areas and de-emphasizing others. Lastly, lighting significantly impacts the mood and atmosphere of a film. By manipulating light intensity, color, and direction, filmmakers can evoke different emotions and enhance the narrative. Bright, even lighting may evoke a sense of safety and happiness, while low-key lighting with shadows can create tension, mystery, or fear. The choice of lighting style can also reflect the genre of the film, such as the high contrast lighting commonly used in film noir.
Cameras have been mounted to nearly every imaginable form of transportation. Most cameras can also be handheld camera, that is held in the hands of the camera operator who moves from one position to another while filming the action. Personal stabilizing platforms came into being in the late 1971s through the invention of Garrett Brown, which became known as the Steadicam. The Steadicam is a body harness and stabilization arm that connects to the camera, supporting the camera while isolating it from the operator's body movements. After the Steadicam patent expired in the early 1990s, many other companies began manufacturing their concept of the personal camera stabilizer. This invention is much more common throughout the cinematic world today. From feature-length films to the evening news, more and more networks have begun to use a personal camera stabilizer.
The 1896 movie The Execution of Mary Stuart shows an actor dressed as the queen placing her head on the execution block in front of a small group of bystanders in Elizabethan dress. The executioner brings his axe down, and the queen's severed head drops onto the ground. This trick was worked by stopping the camera and replacing the actor with a dummy, then restarting the camera before the axe falls. The two pieces of film were then trimmed and cemented together so that the action appeared continuous when the film was shown, thus creating an overall illusion and successfully laying the foundation for special effects.
This film was among those exported to Europe with the first Kinetoscope machines in 1895 and was seen by Georges Méliès, who was putting on magic shows in his Théâtre Robert-Houdin in Paris at the time. He took up filmmaking in 1896, and after making imitations of other films from Edison, Lumière, and Robert Paul, he made Escamotage d'un dame chez Robert-Houdin (The Vanishing Lady). This film shows a woman being made to vanish by using the same stop motion technique as the earlier Edison film. After this, Georges Méliès made many single shot films using this trick over the next couple of years.
The ghost effect was done by draping the set in black velvet after the main action had been shot, and then re-exposing the negative with the actor playing the ghost going through the actions at the appropriate part. Likewise, the vision, which appeared within a circular vignette or matte, was similarly superimposed over a black area in the backdrop to the scene, rather than over a part of the set with detail in it, so that nothing appeared through the image, which seemed quite solid. Smith used this technique again in Santa Claus (1898).
Georges Méliès first used superimposition on a dark background in La Caverne maudite (The Cave of the Demons) made a couple of months later in 1898, and elaborated it with many superimpositions in the one shot in Un Homme de têtes (The Four Troublesome Heads). He created further variations in subsequent films.
However, by varying the speed at which the image is captured, various effects can be created knowing that the faster or slower recorded image will be played at a constant speed. Giving the cinematographer even more freedom for creativity and expression to be made.
For instance, time-lapse photography is created by exposing an image at an extremely slow rate. If a cinematographer sets a camera to expose one frame every minute for four hours, and then that footage is projected at 24 frames per second, a four-hour event will take 10 seconds to present, and one can present the events of a whole day (24 hours) in just one minute.
The inverse of this, if an image is captured at speeds above that at which they will be presented, the effect is to greatly slow down (slow motion) the image. If a cinematographer shoots a person diving into a pool at 96 frames per second, and that image is played back at 24 frames per second, the presentation will take 4 times as long as the actual event. Extreme slow motion, capturing many thousands of frames per second can present things normally invisible to the human eye, such as bullets in flight and shockwaves travelling through media, a potentially powerful cinematographic technique.
In motion pictures, the manipulation of time and space is a considerable contributing factor to the narrative storytelling tools. Film editing plays a much stronger role in this manipulation, but frame rate selection in the photography of the original action is also a contributing factor to altering time. For example, Charlie Chaplin's Modern Times was shot at "silent speed" (18 fps) but projected at "sound speed" (24 fps), which makes the slapstick action appear even more frenetic.
Speed ramping, or simply "ramping", is a process whereby the capture frame rate of the camera changes over time. For example, if in the course of 10 seconds of capture, the capture frame rate is adjusted from 60 frames per second to 24 frames per second, when played back at the standard movie rate of 24 frames per second, a unique time-manipulation effect is achieved. For example, someone pushing a door open and walking out into the street would appear to start off in slow-motion, but in a few seconds later within the same shot, the person would appear to walk in "realtime" (normal speed). The opposite speed-ramping is done in The Matrix when Neo re-enters the Matrix for the first time to see the Oracle. As he comes out of the warehouse "load-point", the camera zooms into Neo at normal speed but as it gets closer to Neo's face, time seems to slow down, foreshadowing the manipulation of time itself within the Matrix later in the movie.
Cecil Hepworth improved upon this technique by printing the negative of the forward motion backward, frame by frame, so that in the production of the print the original action was exactly reversed. Hepworth made The Bathers in 1900 in which bathers who have undressed and jumped into the water appear to spring backward out of it, and have their clothe magically fly back onto their bodies.
The use of different camera speeds also appeared around 1900. Robert Paul's On a Runaway Motor Car through Piccadilly Circus (1899), had the camera turn so slowly that when the film was projected at the usual 16 frames per second, the scenery appeared to be passing at great speed. Cecil Hepworth used the opposite effect in The Indian Chief and the Seidlitz powder (1901), in which a naïve Red Indian eats a lot of the fizzy stomach medicine, causing his stomach to expand and then he then leaps around balloon-like. This was done by cranking the camera faster than the normal 16 frames per second giving the first "slow motion" effect.
In the film industry, the cinematographer is responsible for the technical aspects of the images (lighting, lens choices, composition, exposure, filtration, film selection), but works closely with the director to ensure that the artistic aesthetics are supporting the director's vision of the story being told. The cinematographers are the heads of the camera, grip and lighting crew on a set, and for this reason, they are often called directors of photography or DPs. The American Society of Cinematographers defines cinematography as a creative and interpretive process that culminates in the authorship of an original work of art rather than the simple recording of a physical event. Cinematography is not a subcategory of photography. Rather, photography is but one craft that the cinematographer uses in addition to other physical, organizational, managerial, interpretive. and image-manipulating techniques to effect one coherent process. In British tradition, if the DOP actually operates the camera him/herself they are called the cinematographer. On smaller productions, it is common for one person to perform all these functions alone. The career progression usually involves climbing up the ladder from seconding, firsting, eventually to operating the camera.
Directors of photography make many interpretive decisions during the course of their work, from pre-production to post-production, all of which affect the overall feel and look of the motion picture. Many of these decisions are similar to what a photographer needs to note when taking a picture: the cinematographer controls the film choice itself (from a range of available stocks with varying sensitivities to light and color), the selection of lens focal lengths, aperture exposure and focus. Cinematography, however, has a temporal aspect (see persistence of vision), unlike still photography, which is purely a single still image. It is also bulkier and more strenuous to deal with movie cameras, and it involves a more complex array of choices. As such a cinematographer often needs to work cooperatively with more people than does a photographer, who could frequently function as a single person. As a result, the cinematographer's job also includes personnel management and logistical organization. Given the in-depth knowledge, a cinematographer requires not only of his or her own craft but also that of other personnel, formal tuition in analogue or digital filmmaking can be advantageous.
