Similar effects, some related to red-eye effect, are of several kinds: In many flash photographs, even those without perceptible red-eye effect, the tapetum lucidum of many animals' pupils creates an "eyeshine" effect. Although eyeshine is an unrelated phenomenon, animals with blue eyes may display the red-eye effect in addition to it.
From 1939 to 1963, it was an award for a film's visual effects as well as audio effects, so it was often given to two persons, although some years only one or the other type of effect was recognized. In 1964, it was given only for visual effects, and the following year the name of the category was changed to "Best Special Visual Effects".
Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). [ 1] It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom), hence the prefix photo-.

Skyshine. (Radiation) skyshine describes the ionizing radiation emitted by a nuclear technical or medical facility, reaching the facility's surroundings not directly, but indirectly through reflection and scattering at the atmosphere back to Earth's surface. This effect can happen when the shielding barrier around the source of radiation is ...
Photochemistry. Photochemical immersion well reactor (50 mL) with a mercury-vapor lamp. Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet ( wavelength from 100 to 400 nm ), visible (400–750 nm), or infrared ...
Photoacoustic effect. The photoacoustic effect or optoacoustic effect is the formation of sound waves following light absorption in a material sample. In order to obtain this effect the light intensity must vary, either periodically ( modulated light) or as a single flash ( pulsed light ). [ 1] [page needed][ 2] The photoacoustic effect is ...
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
