A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low ...
Polarizing sheets are used in liquid-crystal displays, optical microscopes and sunglasses.Since Polaroid sheet is dichroic, it will absorb impinging light of one plane of polarization, so sunglasses will reduce the partially polarized light reflected from level surfaces such as windows and sheets of water, for example.
However, this crystal is seldom used as a polarizer, since the dichroic effect is strongly wavelength dependent and the crystal appears coloured. Herapathite is also dichroic, and is not strongly coloured, but is difficult to grow in large crystals. A Polaroid polarizing filter functions similarly on an atomic scale to the wire-grid polarizer ...
Kirlian photograph of two coins. Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.

Polaroid marketers incorrectly guessed that the camera and film would remain in stock long enough to manufacture a second run based on customer demand. All fifty-seven cameras and all of the film were sold on the first day of demonstrations. During his time at Polaroid, Land was notorious for his marathon research sessions.
In 1991, police discovered Jeffrey Dahmer had 84 polaroid photos depicting 17 murders he committed between 1978 to 1991. The act is shown in 'Monster: The Jeffrey Dahmer Story' on Netflix.
In graphic art film, also called lithographic film which is a special type of black and white film used for converting images into halftone images for offset printing, a developer containing methol-hydroquinone and sulfite stabilizers may be used. Exposed silver halide oxidizes the hydroquinone, which then oxidizes a nucleating agent in the ...
Per Biography, "He frequently took photos of his victims at various stages of the murder process, so he could recollect each act afterward and relive the experience." Why did Jeffrey Dahmer take ...
