Green Screen Hollywood – Brief History
Green screen Hollywood technology, a. K. A chroma key is a system employed by filmmakers to mix two separate photographs together. This works by making the background ( a solid color which is mostly green or blue ) clear in order to show another image which is the particular background that’ll be shown on film. This technique 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 technique is also used by filmmakers and photographers alike.
