PZ 600 Silver Shade Cool is balanced for daylight and flash exposure. * 8 exposures per pack. * 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 Spectra and Image series cameras
