The image appears reversed from left to right. Electronic devices inside the cameras automatically adjust the focus, set the light exposure and the shutter speed, and advance and rewind the film. A built-in electronic flash automatically supplies light when too little light reflects off the subject. These cameras are popular among amateur photographers. Some of them have a zoom lens.
View cameras are the largest and most adjustable type of camera.
Most have an accordionlike body, with a replaceable lens in front. They have a large viewing screen instead of a viewfinder. Most models have an adjustable diaphragm and shutter speed. 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.
