Polaroid Camera
In the past, one of the most frustrating aspects of amateur photography was having to use up an entire roll of film and then waiting to have it developed. Polaroid solved that problem with the Swinger in 1965. For only $19.95, the camera not only developed each of its own photographs in only 60 seconds, it also featured a viewfinder that said “YES” when the light was just right for snapping a picture.
