Abstract
A microfilm camera using an instant image film, such as a vesicular film, is herein disclosed. Instant developing stations and an associated read-out optical system are positioned in the path followed by the film as it travels through the camera. After the film is developed, its image is projected through the optical system onto a display screen. This way the operator may see the images immediately after they are formed on the film and rephotograph any defective image immediately.
