VARIATIONS - The variations that make up the 496 total virtual sets consist of different angles of the same set and or different lighting scenarios (colors lighting intensity etc for mood change) and also include some blurs.
BLURS - Most of the sets include a blurred version so you can give the illusion of being farther away from the background. Sometimes this gives greater realism to the set when it's blurred. It is a matter of personal opinion as to which way is better so we include both most of the time.
LIGHTING FOR CHROMAKEY - To get the best shot, light your subjects and the background separately. A green or blue background works best. We use a green cloth or elitevideo.com's pop-out green background. You can use $35 quartz lights on stands that you can get at the local Home Depot type store or you can use a soft light on your subject. You can also use the cloth outside and if the natural lighting is good (the more overcast the better) you can key it in later when using your non linear system. Final Cut Pro, Adobe Premiere, Avid, Avio and Kron systems all have chromakey ability.
