Night Shift is a built in software feature of iOS and macOS.It was introduced in 2016–2017 into iOS in iOS 9.3 and into macOS in macOS Sierra 10.12.4. [1] The feature changes the color temperature of the display towards the warmer part of the color spectrum [2] that reduces some of the blue light from the screen. [3]
The program is free software and is intended to reduce eye strain, as well as insomnia [3] (see Sleep § Circadian clock and Phase response curve § Light). Redshift transitions the computer display's color temperature evenly between daytime and night temperatures to allow the user's eyes to slowly adapt.
Zinc sulfide with about 5 ppm of a copper activator is the most common phosphor for the glow-in-the-dark toys and items. It is also called GS phosphor. Mix of zinc sulfide and cadmium sulfide emit color depending on their ratio; increasing of the CdS content shifts the output color towards longer wavelengths; its persistence ranges between 1 ...
Cryoluminescence, the emission of light when an object is cooled [6] (an example of this is wulfenite) Photoluminescence, a result of the absorption of photons Fluorescence, traditionally defined as the emission of light that ends immediately after the source of excitation is removed. As the definition does not fully describe the phenomenon ...
Night Shift is a video game developed by Attention to Detail and published in 1990 by Lucasfilm Games. It is an action game where the hero is a worker in a factory owned by Industrial Might and Logic (a parody of Industrial Light & Magic ).
Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity.
Radioluminescence is the phenomenon by which light is produced in a material by bombardment with ionizing radiation such as alpha particles, beta particles, or gamma rays. Radioluminescence is used as a low level light source for night illumination of instruments or signage.
Such a substance will then emit light of gradually decreasing intensity, ranging from a few seconds to up to several hours after the original excitation. [ 4 ] Everyday examples of phosphorescent materials are the glow-in-the-dark toys, stickers, paint, and clock dials that glow after being charged with a bright light such as in any normal ...
