This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
This is one of the largest collections of public domain images online (clip art and photos), and the fastest-loading. Maintainer vets all images and promptly answers email inquiries. Open Clip Art – This project is an archive of public domain clip art. The clip art is stored in the W3C scalable vector graphics (SVG) format.
A common thermal light source in history is the glowing solid particles in flames, but these also emit most of their radiation in the infrared and only a fraction in the visible spectrum. The peak of the black-body spectrum is in the deep infrared, at about 10 micrometre wavelength, for relatively cool objects like human beings. As the ...
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.

"An uncertified term: Light Art had naturalised itself recently, without being fit for a term of either a genre, nor a style: in many symbiotic relations, light plays too many roles, and artificial light made itself only the source of inspiration instead of naming it in the countless isms that are drawing on it."

Port with the disembarkation of Cleopatra in Tarsus (1642), by Claude Lorrain, Musée du Louvre, Paris. Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and ...
However, it does explain why the distance of artificial sources affects the character of lighting and lighting strategies in ways not seen in nature. [6] If the distance of a light source is changed in the following distance increments 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45, 64 the intensity will decrease by one f/stop. [3]
