What is the difference between the Virtual Backgrounds system and “green screen” type of electronic backgrounds?
The Virtual Backgrounds system is an optical background projection system. It is relatively inexpensive, simple to use, and extremely effective in quickly producing high quality perfectly realistic results. Blue screen, also known as green screen, chromakey and electronic backgrounds is a comparatively expensive and complex electronic process that superimposes a background in a digitized scene. This means the photographer must be using a digital camera or the film must be digitized after processing. The results are very effective for television work such as the evening weather cast but the results are more limited for producing studio portraits. However, the Virtual Backgrounds system can project a blue screen or green screen or whatever color screen desired. A patent has been awarded on this approach. This development means that your Virtual Backgrounds system can be used for generating optical backgrounds and electronic backgrounds. For a comparison chart click here.
