context_page_description: Bloom is a computer graphics effect used in video games, demos, and high dynamic range rendering to reproduce an imaging artifact of real-world cameras. The effect produces fringes 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. It became widely used in video games after an article on the technique was published by the authors of Tron 2.0 in 2004.
context_section_description: 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 an extremely bright light overwhelming the camera or eye capturing the scene. It became widely used in video games after an article on the technique was published by the authors of Tron 2.0 in 2004.
caption: An example of bloom in a computer-generated image (from Elephants Dream). The light on the bright background bleeds on the darker areas, such as the walls and the characters.
