View cameras must be mounted on a stand for efficient operation. A photographer focuses a view camera by moving the lens end or the back end of the camera forward or backward to produce a sharp image on the viewing screen. Adjustments in the tilt of the camera give the photographer great control over the image. A view camera can provide artistic distortions of a subject more effectively than any other kind of camera. Many professional photographers use a view camera for portraits and other subjects.
Instant cameras use film that provides a print without first being developed into a negative.
The cameras produce a print 15 seconds to 2 minutes after the photographer takes a picture. The time varies according to the camera and the type of film. Special types of film for instant cameras also provide negatives. Some instant cameras can take flash pictures and focus automatically. Electronic cameras, including digital cameras, create pictures that can be viewed on a television screen or transferred to a computer.
