This pack of Polaroid Round Frame Color 600 Film contains 8 instant color photos. Instead of the classic square frame it has a round shaped frame as shown on the front of the box. It is designed for use with vintage Polaroid 600 cameras or it can be used along with a ND filter in your SX-70 camera. This film is rated at an ISO of 640. To improve your results we recommend allowing it to develop in a place where it is shaded from direct light for about 15 minutes after the initial exposure (pockets work well).
