Many pocket cameras such as the 110 camera, are described as small format. In this context, `format' refers to the size of film the camera is intended to hold. The main criticism of this type of camera is that the created negative is so small, and if enlargements more than 6 by 8 inches (15 by 20 centimetres) are required, the print will begin to expose the structure of the film. This means that the print will take on a `grainy' appearance, and in turn destroy any fine details which may be present in the picture.
The 110 camera has a single-speed shutter, which when pressed, allows the image seen through the viewfinder to be exposed onto the cartridge film. This differs from an SLR type camera in as much as the image exposed on the film via the lens is a slightly different image than the one seen by the operator through the viewfinder. All pocket cameras support a built-in flash and many even sport a simple one step telephoto system.
