Abstract
Diffusing light illuminating a light target or subject of a film or video production including placing a diffusion panel between a light source and a light target, energizing said light source so as to direct light therefrom through the diffusion panel, and electrically adjusting the transparency of the diffusion panel by changing an electric potential applied to electrodes of the diffusion panel. The electrically adjustable diffusion panel eliminates the need for manually changing diffusion papers or other filters and provides a continuous range of selectable levels of transparency/diffusion.
