At the heart of blue and green digital backdrops lies the principle of chroma keying, also known as color keying or green screen technology. This technique involves isolating a specific color in a video or image and replacing it with another image or video.
Color Selection: Blue and green are commonly used for chroma keying due to their rarity in human skin tones, making it easier for software to accurately isolate the subject from the background.
Software Processing: Chroma keying software analyzes the video or image, identifying and isolating the chosen color (blue or green).
Background Replacement: The isolated color is then replaced with a new background, seamlessly integrating the subject into a different environment.
