Only a few years ago, photographers & 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 & versatile enough to leave plenty of room for individual inspiration & creativity. These filters can be used with SLR, 24x 26 & Medium Format cameras, wide-angle & tele-zoom lenses & broadcasting equipment.
