When you need to go light-tight and there is not a dark room available, the DLC 17 x 17" changing bag is the answer. The changing bag allows you to remove film from cameras, load bulk film into bulk film loaders, or load sheet film into cut-film holders. Made of high-quality rubberized material with elastic around the arm inserts to prevent light entering, this changing bag is totally lightproof and double zippered for extra protection.
