The Charen Group (www.charengroup.com)has become a model of efficiency; by combining green screen techniques with their prompter people products that they don’t go on location any more. Walter Charen said “We’ve been using your products for about 18 months to make TV commercials… before it took us most of a day to shoot three commercials. Now, we can do eight or ten within three or four hours, and that includes costume changes and lighting adjustments… we won’t do any more commercials without it.”
