Blue Screen 1980

A blue-screen effect in film and video techniques such as chromakey a blue (or green) background in front of which moving subjects are filmed and which allows a separately filmed background to be added to the final image.

This technique is also referred to as color keying, colour-separation overlay, or by various terms for specific color-related variants such as green screen, and blue screen chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds.

You can’t find out much about this obsolete process on the net, so I wanted to add to the information available through my own hands on experience. These were the good old days for sure! Hope you enjoy and learn some new things from this video!
7/19 – CORRECTION – I have mistakenly awarded an Oscar to Petro Vlahos for “The Thief of Baghdad” – that award went to Lawrence Butler in 1941. Vlahos modified and improved Butler’s process on “Ben Hur” and in 1965 won an Academy Award of Merit for his color difference matting system. This will be corrected in the final version of “Blue Screen 1980”
