Development of Green Screen Studio Magic

By Phillip Guye

Green screen studio technology for visible effects grew up with the film industry technology every advancement in film technology benefited and improve green screen studio technology. In developing this type of technology ( otherwise known as Chroma Key Technology ) the color first used was blue like green, blue is the less like human skin tones. Over the years green has proved to be better than blue when it comes to outdoor filming. Today with computerization of chroma key technology, it is possible to use more colors rather than green and blue. At first Green screen studio was essentially used for weather reports as chroma key technology advanced it became well liked by film producers and photographers.

Green screen studio technology has several pioneers in developing and improving this technology. Before PC compositing, the process was complicated and lengthy, and was known as traveling matte. The traveling matte and green chroma key methodology were developed at RKO Radio photos and other studios in the 1930's. At RKO studio Linwood Dun use the traveling matte process to create "wipes" ; which, makes transitions like a windshield wiper in films and was first employed in the 1933 movie Flying Down to Rio. Larry servant is given credit for the development of Chroma Key special effects first used for the flick The thief of Bagdad which claimed him an Academy Award for special effects. Larry butler invented the green screen and traveling matte technique to develop visual effects that were rare in 1940. Butler was the first special effects designer to develop special effects using the specialized screen for Technicolor still in the infancy stage at the time. In 1950, Warner brothers hire an ex-Kodak researcher name Arthur Widmer who commenced developing an ultra violet traveling matte process and improving new Chroma Key systems. The 1st film produce to use the new technology was The Old Man and the Sea in 1958.

Advancement in technology continues to improve the green screen studio computer effects. In the 1980's with the introduction of PCs the method of merging two different pictures together using an optical printer a lot less complicated, during the filming of The Empire Strikes Back, Richard Edlund develop the quad optical printer. Making compositing straightforward, faster, and cost saving that won Richard Edlund a special Academy Award for his invention.

As green screen studio improvements occur many apartments make heavy use of it's studio technology to add backgrounds like computer-generated imagery ( CGI ). Compositing has gotten simpler allowing for pictures from different performances from different takes, and motion to be merged into one scene. Green screen studio makes it possible for filming location shots without leaving the studio which saves the high costs of location filming. Further developments of PC software and computational has eliminated the necessity to use grids or tracking marks.

In closing advances and improvements in technology to green screen studio occurs makes the utilization of it's technology easier and better for creating special visible effects. Today anybody can use a chroma key studio at home for adding visible effects to their own photos. What makes this type of studio possible is a purchase of a chroma key studio setup with computer software less than $200. This makes it simpler for pro photographers to create their own backgrounds or visible effects without the raised costs of filming on location.
