Vidguy thanks so much for the photo lab information. The little I know about it matches what your wrote. I do know that most labs were really too busy to do more than glance randomly at pictures on roll film. We lived in small town midwest where porn and sexy clothes were still frowned on by the general public.
We always thought we were among the rare perverts taking risque photos but later found out we were really normal. Still more were a few steps ahead of us in the risque Polariod picture taking game.
All of the following has been written several other places here.
Our local drug stores sometimes did their own developing which helped when Dollie knew some of the girls who enjoyed seeing our nudie photos. They loved developing and looking at our photos. I'm sure they also may have kept a few copies. We didn't care.
We were into topless and sometimes nudes of either of us. Nothing what we'd call porn. In fact until later we never took pornographic photos. We were into flashing and getting pictures with like minded strangers with Dollie or sometimes even me nude with a pretty naked female.
Seems like often even those local drug store labs sent many rolls of film out, I'd swear Florida, for processing. Rarely any skin photos came back. I always wondered what happened to the real pictures. We often got black or all white prints instead of the many pictures we spent hours taking. I'm sure most were just destroyed. I do remember occasional notes saying those photos just didn't come out.
A new small photo lab opened in town and Dollie became friends with the older owner and soon the horney young son who worked there. With me, his, and other encouragement I was now taking near porn photos with strangers doing hands-on photo poses with my wife. As I wrote before, the young pervert was caught selling women's photos to dirty magazines.
Something else, our first film cameras, 110 film I believe, had built in flashes. Those took a small flash bulb that had to be removed each time for another. Picture taking was slow and awkward yet in the 60's-70's. Lucky for me dad and his friend set me up with my own lab to process and develop B & W photos. This was when we did take some porn type pictures to swap and give away. Those would have qualified for old pics.
Somewhere during all of this flashing and taking pictures to prove it, I discoverd black and white Polaroid cameras. A whole new world for perverts eveywhere. Then came the small cheap color film Polaroids. Still when hiking nude or partially naked in the woods or along a beach, carrying a fairly large camera, a supply bag, and an extra 10-pack of film was not the greatest thing. Especially while sweating and covered with sunscreen.
Since joining OCC and looking at many other threads we are amazed how many others in our age group still have those old Polaroid pictures. Ours are all long gone for various reasons.
Sorry for another long

winded story.
