Green Screen is a technique used in photography or video productions for mixing images from two frames together. This process is perhaps most known for its use in weather forecasts. Chroma key green screen backdrops are perfect for including special effects.

The green screen backdrop fabric must be finished on all four sides. Green screen backgrounds fabric normally also has useful pocket rods and seams. It can be machine washed as well.
A portable green screen is especially handy for photographers who often do location shoots. Using a green screen background fabric is definitely more practical than using a large television for presentations. Even TV stations prefer this technique for its low cost.
