Green screen Hollywood technologies, also called chroma key is a method utilized by filmmakers to blend 2 separate pictures with each other. This succeeds by causing the background (a solid color which is typically green or blue) transparent so that you can reveal another picture that is the actual backdrop that will be revealed on film. This process of filming is also known as color keying, blue screen, and color separation overlay (CSO). It was mostly used for weather reports. Forecasters were filmed in front of chroma key screens and the backdrop was swapped out by real maps which indicate weather predictions. The chroma key technique is additionally used by filmmakers and professional photographers alike.
The green screen first had its appearance in the 1930′s at RKO Radio Pictures. The backdrop used back then was blue. This method of motion picture making was created in order to create special effects for the film “The Thief of Bagdad.” Aside from the chroma key technique, filmmakers depended on a very tiresome and time intensive process called “travelling matte.” This made transition just like “wipes” achievable.
Larry Butler is considered responsible for revolutionizing the blue screen approach. Actually, he even took home an Academy Award for visual effects with regard to his work in “The Thief of Bagdad.” After his accomplishment in the 30′s, Butler was the very first individual to make use of chroma key technology in Technicolor, paving the way for contemporary green screen Hollywood technology.

After the “Old Man and the Sea,” a lot more films utilized the chroma key approach. A number of popular film which make use of chroma key technology are The Empire Strikes Back, Lord of the Rings, Titanic, Star Trek, as well as 300.
