Pinhole Photography is the simplest form of photography. It’s basically a camera with a pinhole for a lens. A pinhole camera is pretty easy and dates back to 1544 when an astronomer made a pinhole camera to make images of a solar eclipse. Modern photographers often make or buy a pinhole lens for their digital camera. It’s easy to do, but it takes a lot of patience.
I use a homemade maple box that takes 4×5 sheet film in traditional holders or a Polaroid 4×5 back for peel apart film. My pinhole lens is made from a very thin piece of brass. You can buy very nice cameras at specialty camera stores that use traditional roll film.
