Green screen Hollywood technology, also called chroma key is actually an approach used by filmmakers to blend 2 separate pictures with each other. This works by causing the background (a strong color which is usually green or blue) transparent so that you can reveal another image which is the specific backdrop that will be shown on film. This method of filming is also called color keying, blue screen, and color separation overlay (CSO). It was primarily used by weather reports. Weather forecasters got shot before chroma key screens and the backdrop was replaced by real maps that indicate weather predictions. The chroma key method is additionally employed by filmmakers and professional photographers as well.
The green screen initially made its appearance in the 1930′s at RKO Radio Pictures. The particular background used in those days had been blue. This method of motion picture creating was developed in order to create special effects for the film “The Thief of Bagdad.” Apart from the chroma key method, filmmakers depended on a very tedious and time intensive procedure referred to as “travelling matte.” This made transition such as “wipes” possible.
Larry Butler is known to be responsible for pioneering the blue screen technique. In fact, this individual actually took home an Oscar for visual effects with regard to his work in “The Thief of Bagdad.” After his success in the 30′s, Butler was the first person to utilize chroma key technologies in Technicolor, paving the way for contemporary green screen Hollywood technology.
The very first movies to take advantage of Chroma Key technology was the film adaptation of Ernest Hemingway renowned novella, “The Old Man and the Sea,” starring Spencer Tracy. Following on from the “Old Man and the Sea,” more and more films utilized the chroma key technique. Some popular film which take advantage of chroma key technology are The Empire Strikes Back, Lord of the Rings, Titanic, Star Trek, and even 300. Films that make use of CGI or computer generated pictures are also created with the aid of green screen technology. This is how obtaining out of our planet settings and awesome creatures are able to be presented on film.
These days, green screen Hollywood technology isn’t just confined to big budget studios. It is also utilized in photography. Through the original blue screen, green was used afterwards because filmmakers discovered a green background doesn’t need tedious lighting. Cameras are most sensitive to this color, so the outcome of movies taken on green screens are usually easier to work with and manipulate. With that said, chroma key technological know-how has become identified to photographers and filmmakers’ greatest friend.
