  2. Polavision - Wikipedia

    en.wikipedia.org/wiki/Polavision

    Polachrome was a color slide film. It was descended from the Polavision system and used the same additive color ( RGB filter stripe) process. One difference was that with Polavision, the negative layer remained as part of the film after processing. It was of low optical density (max. 0.3), but nevertheless reduced the contrast of the image.

  3. Image stabilization - Wikipedia

    en.wikipedia.org/wiki/Image_stabilization

    Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

  4. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]

  5. Anamorphic format - Wikipedia

    en.wikipedia.org/wiki/Anamorphic_format

    Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the ...

  6. Exposure compensation - Wikipedia

    en.wikipedia.org/wiki/Exposure_compensation

    Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image. Factors considered may include unusual lighting distribution, variations within a camera system, filters, non-standard processing ...

  7. Sodium vapor process - Wikipedia

    en.wikipedia.org/wiki/Sodium_vapor_process

    The camera was a retired Technicolor three-strip camera modified to use two films and used normal lenses for the conventional 1.85:1 aspect ratio. [citation needed] First developed in 1932, Technicolor three-strip cameras ran three rolls of black-and-white film past a beam splitter and a prism to film three strips of film, one for each primary ...

  8. High-speed photography - Wikipedia

    en.wikipedia.org/wiki/High-speed_photography

    Muybridge's photographic sequence of a race horse galloping, first published in 1878.. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...

  9. Photographic processing - Wikipedia

    en.wikipedia.org/wiki/Photographic_processing

    Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.
