Evolution of Photography : Exposures Versus Keepers
Photographer Mason Resnick created this humorous (but perhaps painfully true?) graphic about how photography has changed since the days of 12-exposure rolls of 120 film.
Resnick was cleaning out his office when he found an unopened roll of 120 film from the 1950s, a metal 35mm film canister, and a modern SD memory card. That got him thinking, and he decided to have a little fun by creating this meme image.
Here is another interesting pictorial showing the evolution of Cameras.
