A light leak, commonly associated with Holga model cameras, is an area within a camera where light is able to seep, or "leak", in, causing the film to over-expose. Within most cameras, this is considered a major problem, usually remedied through replacement of the foam between the back of the camera and the camera body. Within Holga cameras specifically, the most common light leak areas are located at the corners of the front of the camera, the seams between the back and the body of the camera, and the exposure number window on the back of the camera. Some people consider the light leaks in cameras such as the Holga model to be artistic and therefore leave the light leaks untouched. Others, however, see them as a nuisance and cover them with Velcro, duct tape, or electrical tape.
