Polaroid SLR 680. PX 70 Color film from The Impossible Project. The Impossible Project is trying to develop instant film for Polaroid cameras. Polaroid no longer makes instant film.

PX 70 Color film is the latest color film. It was designed for Polaroid SX70 cameras. However, the asa of this film is probably something like 400. The SX70 takes asa 125. Therefore, without neutral density filters, turning the L/D wheel all the way to dark and shooting in low light, the photos are overexposed.

This film works lovely in Polaroid 600 cameras though. You just set the L/D wheel to light. It is a much better fit for the film.
