Understand that until digital photography came along everything, except Polaroid, had to be left at a drug store, photo lab, or somewhere outside the home and often outside the town to a labor-intensive photo developing lab.
Other people developed the film in majority of cases. You COULD be in trouble if they saw something they shouldn't.
When my father was in middle school in the 1970s $500 bills were still in general circulation. His grandfather on his father's side gave him one as a birthday present a couple of times when he was in his 'teens. The first time he actually photographed it! Lucky for him when his father picked up the pictures, it was explained to him in no uncertain terms why he was lucky the whole roll hadn't been destroyed! Also that the Secret Service HAD been notified, and they were the ones who identified it as the work of a kid who probably didn't know any better, there for the decision was to only destroy those two negatives.
Polaroid was a very expensive way to take pictures. As a result it was often only used on the most special occasions.That actually turned out to be a mistake because the pictures faded so much faster than ordinary prints.
As tight-fisted and downright penurious as his parents were, Polaroid was out of the question.
Even with an Instamatic he had to buy most of his own film, and he says it was always an argument about the cost of getting it developed.
And to make matters worse he was big brother to a wise-ass who was always pranking him.
Given that, you don't think it ever crossed his mind to let a camera in the same room with any of his enema equipment, do you??
