Impossible PRD2184 PX 70 Color Shade Cool Film for Polaroid SX-70 Cameras, (Multi-colored) Due to the high filmspeed of this material we recommend adjusting the lighten/darken wheel or slider of your camera 1/3 into the dark setting. This slightly high film speed will yield simply amazing color and tones in your correctly exposed SX 70 pictures. Built in, long lasting battery to power up the camera and flash. As the camera ejects the picture, do IMMEDIATELY shield it from light (e.g. using the Impossible Frog tongue or with your hand, a darkslide, shoot into a box, etc...) - the first half second is crucial! This film is compatible with SX 70 cameras.
