"LOS ANGELES - Arthur Widmer, who developed some of the most widely used special effects technology in films and earned an Academy Award last year for lifetime achievement, has died. He was 92.
The Academy of Motion Picture Arts and Sciences gave Widmer the award for his work in developing Ultra Violet and "blue screen" special effects processes.
"Art's pioneering work has had a profound impact on the film industry," said Richard Edlund of the academy's Scientific and Technical Awards Committee when the award was announced. "Many of the films we hold dear would not have been possible without his contributions to image compositing technology."
Working for Warner Bros. in the 1950s, Widmer developed the Ultra Violet Traveling Matte process, an early version of what would become known as blue screen, in which two different images shot at different times and places could be combined into one."
