System Overview


Until recently, lighting a standard green or blue screen has been cumbersome, attempting to achieve an even color tone, and the results are not always efficient for post-production removal of the background. However, if you are not yet familiar with it, a somewhat newer approach to chromakey production has changed that immensely: The system utilizes a ring of colored LED lights around the camera lens that reflect off of a gray, reflective backdrop. The result is a beautifully smooth wash of color (blue or green, depending on the color of the LED's being used) that makes pulling a great key close to effortless... it is an amazing thing! Just a few of the main advantages over a traditional blue/green chroma key screen setup are:

A perfectly smooth, even wash of color, with adjustable luminance.
No separate lighting needed for the screen. Thus, no excess heat near the talent, and considerably less electricity usage / amperage draw.
Easy portability, less gear to haul around, lightning quick setup.
Allows certain applications not possible with a traditional chroma screen.
Very good tolerance for wind / movement, shadows and wrinkles.






This type of system is in use throughout the world in network and broadcast studios, as well as commercial video production facilities. On average, those systems cost about $1,500 to $2,500 for a standard package (which I have owned and used with joy), and several thousand dollars on up for a large, full-body system. Since my video production company has an upcoming project this summer which mandates having much more than my existing 8x8 reflective material on hand, and it was only available in many hundreds of meters, I decided to create a limited number of these systems for sale to, hopefully, help offset the cost, and maybe provide an avenue for this type of system to those who might not otherwise be able to afford it.
