Advanced cameras have a wide range of shutter speeds. A fast shutter speed allows you to capture action scenes. A shutter release to open and close the shutter. A film-advance mechanism to advance the film for the next exposure. A viewfinder to show you the area you are taking pictures of.
Some cameras have a built-in flash, while others have a flash shoe for holding a flash accessory.
Although all cameras are basically the same, some cameras offer certain features that others don't. Simple Cameras To make things easy, we'll call any camera simple if it doesn't offer adjustments for shutter speed, lens opening, and focus, and doesn't have an exposure-control system. Although some simple cameras have a fixed lens opening, others have an adjustment for two or three different lens openings. Set the lens opening according to the recommendations in your camera manual or in the film carton. An adjustable camera has controls that allow you to take pictures under a wider range of conditions than is possible with a non-adjustable camera.
