    The Kanizsa triangle is an optical illusion first described by the Italian psychologist Gaetano Kanizsa in 1955. It is a triangle formed of illusory contours. Kinetic Depth Effect: The Kinetic depth effect is the phenomenon whereby the three-dimensional structural form of a silhouette can be perceived when the object is moving. In the absence ...

    en.wikipedia.org/wiki/Fechner_color

    The Fechner color effect is an illusion of color seen when looking at certain rapidly changing or moving black-and-white patterns. They are also called pattern induced flicker colors (PIFCs). A sample of a Benham's top (animated version) The effect is most commonly demonstrated with a device known as Benham's top (also called Benham's disk ...

    en.wikipedia.org/wiki/Color_photography

    The first color photograph made by the three-color method suggested by James Clerk Maxwell in 1855, taken in 1861 by Thomas Sutton. The subject is a colored ribbon, usually described as a tartan ribbon. Color photography (also spelled as colour photography in Commonwealth English) is photography that uses media capable of capturing and ...

    Optical illusion is also used in film by the technique of forced perspective. Op art is a style of art that uses optical illusions to create an impression of movement, or hidden images and patterns. Trompe-l'œil uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions.

  6. Chromatic aberration - Wikipedia

    en.wikipedia.org/wiki/Chromatic_aberration

    Chromatic aberration also affects black-and-white photography. Although there are no colors in the photograph, chromatic aberration will blur the image. It can be reduced by using a narrow-band color filter, or by converting a single color channel to black and white. This will, however, require longer exposure (and change the resulting image).

    en.wikipedia.org/wiki/Lippmann_plate

    The back of the film is then brought into optical contact with a reflective surface. This originally was done by mounting the plate in a specialized holder with pure mercury behind the film. When it is exposed in the camera through the glass side of the plate, the light rays which strike the transparent light-sensitive film are reflected back ...

  8. Optical phenomenon - Wikipedia

    en.wikipedia.org/wiki/Optical_phenomenon

    Optical phenomena are any observable events that result from the interaction of light and matter. All optical phenomena coincide with quantum phenomena. [ 1 ] Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates.

  9. Jitter (optics) - Wikipedia

    The equation for the optical Modulation transfer function associated with jitter is M T F j i t t e r ( k ) = e − 1 2 k 2 σ 2 {\displaystyle MTF_{jitter}(k)=e^{-{\frac {1}{2}}k^{2}\sigma ^{2}}} where k is the spatial frequency and σ {\displaystyle \sigma } is the amplitude of the jitter. [ 2 ]
