Now that a picture costs no more than a few seconds and some negligible memory space, we take pictures of everything. But long ago, in a strange time known as the eighties and early nineties (and all of time since the beginning of photography before that), you had to choose your photos. The pictures went onto actual rolls of film, and those rolls could only hold so many shots, and then you had to pay someone to turn that film into a picture.
They were different times. People took pictures of different things. Basically, there were almost none of these (graphic courtesy of 20 Pixels):
But hey, the post-digital age is still learning. If we can nix the food shots, cut down on the tickets and new possessions, and just get a little more selective in what gets shared, our Facebook feeds will be thankful for it.
