A Brief History of Green Screen Hollywood
Green screen Hollywood technology, also known as chroma key is a methodology used by filmmakers to mix 2 separate images 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 will be shown on film. This strategy of filming is a. K. A color keying, blue screen, and color separation overlay ( CSO ). It was basically used for weather reports. Forecasters were shot in front of chroma key screens and the background was replaced by actual maps that indicate weather predictions. The chroma key strategy is also utilised by filmmakers and photographers alike.
The green screen first made its appearance in the 1930's at RKO Radio photographs. The backdrop used back then was blue. This method of film making was developed to create special effects for the film "The burglar of Bagdad." apart from the chroma key strategy, filmmakers depended on an awfully tedious and laborious process called "travelling matte." This made transition such as "wipes" possible.
Larry servant is known to be in charge of pioneering the blue screen technique. In reality, he even took home an Academy Award for visual effects for his work in "The burglar of Bagdad." After his pre-eminence in the 30's, servant was the first person to use chroma key technology in Technicolor, paving the way for modern green screen Hollywood technology.
The first films to take advantage of Chroma Key technology was the film adaptation of Ernest Hemingway famous short story, "The Old Man and the Sea," starring Spencer Tracy. After the "Old Man and the Sea," more and more films used the chroma key strategy. Some famous film that make use of chroma key technology are The Empire Strikes Back, Lord of the Rings, Titanic, Star Trek, and even 300. Films that employ CGI or computer generated photographs are also made with the help of green screen technology. This is how having out of this world settings and extraordinary creatures may be able to be shown on film.
Today, green screen Hollywood technology is not just limited to large budget studios. It's also employed in photography. From the first blue screen, green was employed later on because filmmakers discovered that a green background doesn't need tedious lighting. Cameras are most delicate to this color, so the outcome of films shot on green screens are more easy to work with and manipulate. With that said, chroma key technology is now known to photographers and filmmakers' best friend.
