Only a few years ago, photographers and videographers were asking for special effect filters. Today, they ask for COKIN filters. A French professional photographer, Jean Coquin, is the inventor of the concept of creative photography. To allow everybody to get a chance to produce great creative images Jean Coquin designed a system with the following prerequisites : simplicity, rapidity of use and versatile enough to leave plenty of room for individual inspiration and creativity. These filters can be used with SLR, 24x26 and Medium Format cameras, wide-angle and tele-zoom lenses and broadcasting equipment.
