Polaroid Automatic 315
Manufactured from 1969 to 1971 by the Polaroid Corp. of Cambridge, Massachusetts. The “Automatics” added a fully automatic, transistorized electronic shutter that gave continuously-variable shutter speeds. The 315 was a light plastic model that used a simple viewfinder with a distance scale superimposed in the field of view (which was linked with parallax correction to the focusing mechanism). Basically a next generation 210. It did, however, have a plastic lens.
Fun fact: One issue with the Polaroid pack films what that their development time was sensitive to cold. If you took your pictures in the outside winter air, sometimes your pictures turned out too light as a result of the chemical process that migrated the dyes taking too long. About the time of the introduction of the 300 series Automatics, Polaroid introduced the “Cold Clip”—basically two sheets of metal, fabric hinged at one end that you kept in an “inside coat or shirt pocket” and put your developing film in to keep it warm in these situations. By the time SX-70 film rolled around, it would fully develop—although slower—in cold weather, but people would still attempt to keep them warm to make them develop faster. Some would even rub the picture between their hands—giving some odd results that eventually lead to the art of the “manipulated” Polaroid print…
