There was a cracking report on the Today Programme this morning about pinhole cameras. Tomorrow, the last Sunday in April, is apparently World Pinhole Camera Day. There are some great shots on pinholephotography.org and www.pinhole.org which demonstrate nicely the fantastic depth of field obtained thanks to a small aperture and no lens. I'm very tempted to have a crack myself, but after years of using only digital photography i'm loathed to go back to using nasty chemicals.
