Light Blaster Strobe Based Projector allows you to use your shoe mount flash and a Canon EF or EF-S lens to transform an ordinary wall into a creative background of patterns, landscapes, people and places. Use your vacation slides to place your subject in a crowd or on a bridge or in a village square.If slides are unavailable or you just want some fresh material, Spiffy Gear has four creative multiple slide kits for you with everything from haunted houses to vivid patterns to earth in space. There's even a set that will allow you to put your choice of angel or fairy wings on your subject. For Nikon users there's an adapter that lets you share in the fun. The light Blaster comes with a slide cartridge, slide and a Spiffy case.
