Getting a good even color behind the talent is the first step in green screen, this usually requires a chromakey backdrop in the form of cloth or paint. Some green screen paint can be picked up at hardware stores or lighting places like Studio Depot (Burbank, Ca), blue cloth can also be found many places. Some companies sell green screen pop up green screen backdrops which travel easily and popup like a windshield shade.
Another alternative is Chromatte, a unique retroreflective material which is gray to the eye, requires little or no light, and casts no spill on the talent because the material is gray to the naked eye. But to the camera it sees it as a perfect blue or green. This is because of the Litering, a ring of LEDs around the lens which casts blue or green light onto the Chromatte material. Chromatte is also very portable in the form of a Chromaflex, a 7x7 popup which folds down into a 3 foot hoop. Chromatte is superior to Green Screen in many ways.
