The Impossible Project was created by a small group of former Polaroid employees who saved the last Polaroid integral instant film production plant in Enschede, Netherlands. They began inventing and producing a complete line of unique instant film materials designed for traditional, once extinct Polaroid cameras.The PX 100 Silver Shade UV + Instant Film features a special UV filter coating for improved black and white tones. PX 100 Silver Shade  is a monochrome material, optimized for the use in traditional Polaroid SX-70 cameras.
