What is an pinhole camera?
The most common type of pinhole photography is done with the aid of a shoe box. The film (use real black and white film as it is less sensitive to light and light leaks because we are talking about a shoe box here) is taped to one end of a shoe box and a small pinhole is carefully punched into the center of the opposite end of the shoe box. The box lid should be placed on tightly and sealed in place. When you handle the film, you must try to have total darkness. Practice all aspects of putting your shoe box "Camera" together in the light first. Place your finger over the pin hole before bringing into the light. Then the box is placed, usually outside on a sunny day. Point the pinhole end of the box toward something that you are interested in taking a picture of. Your subject has to be something that is stationary. The light coming through the pinhole will expose your film for you. Research the subject to help determine pinhole size and approximate exposure times to take some guesswork out your project.

Of course always test a heated baby bottle before giving to an infant.
