Cinematography (from Greek: kinema - κίνημα "movement" and graphein - γράφειν "to record"), is the making of lighting and camerachoices when recording photographic images for the cinema. It is closely related to the art of still photography. Many additional issues arise when both the camera and elements of the scene may be in motion, though this also greatly increases the creative possibilities of the process.
HISTORY
The first attempt at cinematography can be traced back to the world's first motion picture film,Roundhay Garden Scene.[citation needed] It was a sequence directed by Louis Le Prince, Frenchinventor and showman, on October 14, 1888 in the garden at Oakwood Grange in Roundhay, Leeds,West Yorkshire, England.[citation needed] This groundbreaking event happened seven years before theLumière Brothers' Sortie de l'usine Lumière à Lyon made the first paid exhibition on December 28, 1895 at Le Grand Café, in Paris, France.[citation needed]. This date is known as the birth of cinema since it was the first time the cycle of production-distribution-exhibition happened. The European city soon became the motion picture capital of the world.
Cinematography is an art form unique to motion pictures. Although the exposing of images on light-sensitive elements dates back to the early 1800s (Canadian Geographic), motion pictures demanded a new form of photography and new aesthetic techniques.
In the infancy of motion pictures, the cinematographer was usually also the director and the person physically handling the camera. As the art form and technology evolved, a separation between director and camera operator emerged. With the advent of artificial lighting and faster (more light sensitive) film stocks, in addition to technological advancements in optics and various techniques such as color film and widescreen, the technical aspects of cinematography necessitated a specialist in that area.
Cinematography was key during the silent movie era - no sound apart from background music, no dialogue - the films depended on lighting, acting and set.
In 1919, in Hollywood, the new motion picture capital of the world, one of the first (and still existing) trade societies was formed: theAmerican Society of Cinematographers (ASC), which stood to recognize the cinematographer's contribution to the art and science of motion picture making. Similar trade associations have been established in other countries, too.
The ASC defines cinematography asa 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.
ASPECTS
Film stock
Cinematography can begin with rolls of film or a digital image sensor. Advancements in film emulsion and grain structure have provided a wide range of available film stocks. The selection of a film stock is one of the first decisions they must make during any 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 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 created the "super" variety 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 are all formats that 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 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.
Digital imaging 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, although it is heavily argued as to which method of capturing an image is the "best" method. Digital image adjustments (ISO, contrast etc.) are executed by estimating the same adjustments that would take place if actual film were in use, and are thus vulnerable to the cameras sensor designers perceptions of various film stocks and image adjustment parameters.
FILTERS
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 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 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. Certain cinematographers, such as Christopher Doyle, are well known for their innovative use of filters. Filters can be used in front of the lens or, in some cases, behind the lens for different effects.
François Roland Truffaut (French IPA: [tʀyˈfo]) (February 6, 1932 – October 21, 1984) was one of the founders of the French "New Wave" in filmmaking, and remains an icon of the French film industry. In a film career lasting just over a quarter of a century, he fulfilled the functions of screenwriter, director, producer or actor in over twenty-five films. --
