The Holga 135PC Pinhole Camera is a lens-less camera that has a tiny pinhole in the front. It is operated by pressing the shutter release, holding it open for however long you choose and making long exposures. Don't worry about focus decisions at all.
Make long exposures at night (several hours) or short ones (1 second), but first make the decision about how long to keep the lens open. And using a tripod is a must for these type of long exposures.
Because of its ability to deliver extensive depth-of-field, the foreground and background will almost always be in focus. Images will be soft focus, with a dreamlike quality about them. Use any type film with this camera, be it color, slide, or b&w film.
