Edwin H. Land, former president of the Polaroid Corporation (1947), invented the world’s first instant camera. Here’s how it works:
With his camera, you snap the shutter and turn a knob; 60 seconds later you have a finished, dry print. The Land camera takes its pictures in the conventional way, but inside it, in addition to the film roll, there is a roll of positive paper with a pod of developing chemicals at the top of each frame. Turning the knob forces the exposed negative and the paper together through rollers, breaking the pod and spreading the reagents evenly between the two layers as they emerge from the rear of the camera. Clipped off, they can be peeled apart a minute later
