A Tip A Day [:: ATAD ::]

A pinhole camera works on a simple principle where light enters a small hole to produce an image on the film/sensor. This image is usually sharp, but since only a small amount of light is entering the pinhole, longer exposure times would be required. A pinhole can never replace your camera lens, but such a setup can be used simply for artistic purpose or just to have some fun
