I’m very fond of pinhole photography. I haven’t yet got to the point where I’ve invested in a full blown pinhole camera (which are available) but I have had a camera body cap adapted which turns my DSLR into a pinhole camera.
Basically, a pinhole camera is a camera without a lens. The light is instead allowed through a pinsized hole for a specified amount of time. It takes a bit of trial and error, but the results are lovely. It gives a soft focus retro feel to most subjects. Because long exposures are more or less essential, you will need a tripod, and a timer/release is also very handy.
One of the best companies for pinhole photography paraphernalia and information is Pinhole Solutions (http://www.pinholesolutions.co.uk/index.html) who will convert your body cap into a pinhole lens and provide you with a dial calculator for £35.00. If you want to do the job yourself you can purchase the pinhole shims (yes, the metal bits with the pinholes in them are called shims) for £8.00 for 10.
Give it a go.
