A green screen background is used in chroma key photography.
Chroma key or green screen portraiture has gained popularity with the advancements of digital photography. Usually a subject is photographed against a green chroma key background. Later, that chroma key background can be relatively easily erased and replaced with a different scenic or artistic background using a computer program. There are many software with various features now available that cater to this type of photography
Adobe Photoshop CS5, as of 2010, is the most recent version of Photoshop. Known as one of the most advanced photo-editing software with a steep learning curve, it is the industry-standard graphic software widely used by photo enthusiasts and professionals. For chroma key photography in the CS5 version, according to Adobe, users can "easily select intricate image elements, such as hair; eliminate background color around selection edges; and automatically vary selection edges and perfect masks using new refinement tools."
