These days, the phrase “instant photography” is almost redundant. A photo appears on the screen of your camera (or phone) a moment after you shoot it. And in a lot of cases, the photo can appear on the Internet a moment or two after that.
But it wasn’t always this way. For decades, the phrase “instant photography” meant “Polaroid.” If you didn’t want to wait for film to be developed, you used Polaroid cameras and films, which enabled you hold a finished print in your hand within a minute or two after shooting.
Amateurs loved Polaroid for that very reason: no taking film to the corner drugstore and then waiting. Professional photographers used Polaroid to make test shots. And some, including Ansel Adams, Andy Warhol, and William Wegman, used Polaroids to create enduring works of art.
