Steps in a blue-screen effect
Figure 4: Steps in a blue-screen effect.
The "blue screen" process in photography, also known as chroma-key, is a technique used for compositing images. It involves filming a subject against a solid blue background. This allows for the separation of the subject from its original background, enabling it to be combined with other footage or images. This method is also referred to as a blue screen and is a form of color-based compositing. The term "blue screen of death" refers to a computer error message and is unrelated to this photographic technique.12
