The Light Bloom wiki last edited by daveyd on 09/12/14 04:49PM View full history


Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos and high dynamic range rendering (HDR) 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 an extremely bright light overwhelming the camera or eye capturing the scene.

The bloom lighting effect was introduced to the video game industry by the PS2 titles, The Bouncer, released in 2000, and Ico, released in 2001. The Bouncer used it as a lighting & glowing effect, to create a more cinematic movie-like look, as well as to compensate for the PS2's lack of anti-aliasing. Ico used it to create a more artistic, atmospheric look.

Bloom was later popularized within the computer game development community in 2004, when an article on the technique was published by the authors of Tron 2.0. Bloom lighting has since been used in many games, modifications, and game engines, such as Quake Live, Cube 2: Sauerbraten, and the Spring game engine.

The effect is popular in current generation games, and is used heavily in PC, Xbox 360 and PS3 games, as well as GameCube and Wii releases such as The Legend of Zelda: Twilight Princess and Metroid Prime 2: Echoes, and PS2 games such as Dark Cloud 2 and Shadow of the Colossus. The use of bloom in Fallout 3 and Syndicate (2012) are particularly notorious.
