BLOG 11 (GREEN SCREEN)

As technology advances so does our movie making abilities. The “Chroma Key” (Green/blue screen) was developed in the 1950’s to allow the layering of two images or videos at once. Chroma Key, Chroma meaning color range, easily allows for the removal of a background. However, the technique was did not become widely used until the early 1990’s due to technological limitations. Chroma Key works by using a solid color as a background that can easily be made transparent enabling the ability to add in a second image or video. Some common uses for Chroma Key is showing the weather on the news and movie/TV special effects. 

My favorite move that uses chroma key is Avatar. First of all, that movie ROCKS! and if you haven’t seen it yet, I highly recommend it. But, in regards to chroma key, that movie took it to an extreme. Chroma Key was used throughout the movie enhancing the movies amazing alien planet scenery.
