The Holga 120S is a cheap, medium format, plastic, toy camera. It creates negatives which can be 6x6 cm or 6x4.5 cm. The images tend to have foggy edges and are often quite dreamlike. No two Holgas take pictures in quite the same way. Many people buy several at one time. Taping the camera with gaffers tape or camera tape will help to cut down on the light leaks.
