Svema Mz3  is a black & white, blue sensitive film rated at ISO 3. Photographer Larry Buechler described the film as "slow, wonderful, fine grain and super sharp." He went on to say that Mz3 produces "creamy, dreamy highlights that seem to float on the image like a mist." 
How to shoot ISO 3? A manual 35mm slr camera is recommended. Use a smart phone light meter app, use our Black Cat Exposure Guide or use a hand-held light meter.
