A Brief History of Green Screen Hollywood
Green screen Hollywood technology, AKA chroma key is a technique used by filmmakers to mix two separate pictures together. This works by making the background ( a solid color which is mostly green or blue ) transparent in order to show another image which is the actual background that’ll be shown on film. This method of filming is often referred to as color keying, blue screen, and color separation overlay ( CSO ). It was essentially used for weather reports. Forecasters were shot in front of chroma key screens and the background was replaced by actual maps that indicate weather forecasts . The chroma key strategy is also used by filmmakers and photographers alike.
