|ANGEL||A person who invests in a prospective production.||Backer|
|GEL||Short for gelatin, the material once used for color filters. A sheet of plastic usually composed of a colored resin sandwiched between two clear pieces. The colored filter absorbs all the colors of light except the color of the filter itself, which it allows through. For this reason, denser colors get very hot, and can burn out very quickly. At one time, filters were made from gelatin, from which came the still-used name "gel." Also known as a color filter, and manufactured and sold as such by companies like Rosco.|
|GEL FRAME||A frame which holds the color filter in the guides at the front of a lamp. Many different sizes of frames are needed for the different lamps.|
