Food staging is a whole industry in and of itself. Those gorgeous shots of finished food items in magazines may not even be edible! To make a smoothie last long enough to complete an infomercial, it must be made of something that will maintain the look and color of the finished product. Real ingredients will get warm and begin to separate quickly under the lights. 3 cheers for KCTS and and all you do in supporting home cooks and home photography of their products, and more importantly for keeping this part of 'public' in public TV!
