<br> Tutorial Description - Introduction to Chromakeying
Chromakeyer is basically a device which replaces everything of one particular colour with parts of another picture. This technique is known to most people, although normally they refer to it as "green screening" or something similar.
Chromakeyer is basically a device which replaces everything of one particular colour with parts of another picture. This technique is known to most people, although normally they refer to it as "green screening" or something similar. Keying (there are other varieties, such as luma-keying or green screen keying) is used in a huge variety of films and television programmes to achieve all sorts of effects.
Almost every time you see a close up of Harrison Ford dangling off a cliff in Indiana Jones, it is chromakeyed. All that stuff in The Matrix was chromakeyed (although they had a lot of other stuff going on too). Pretty much every scene in Star Wars episode one was keyed together (excluding the ones that didn't exist outside a computer in the first place), and then Jar-jar Binks was keyed on top of that (unfortunately).
