Welcome! How is France tis time of year? Here is a link to a french discussion group you can try as well. Some of the best holographers are in France. A new 3-color silver halide film is being produced there called Ultimate. I use a red sensitive silver-halide film from Russia. I have also designed embossed holograms like the ones you see on packages like videos. Also you will find photopolymers. Those are the three types I have seen in person. There are others. Silver-halide - Cost:High - Depth:great - Easy in small #s Photo-polymer - Cost:medium - Depth:good - Can't buy film embossed - Cost:low - Depth:poor - must do large numbers
