Earlier in the year I ventured into the world of Pinhole photography. This image of Brighton’s now dead West Pier was shot using a Titan Harman 5×4 Pinhole camera at an aperture of f206 with an exposure of 90 seconds using Fomapan 100 5×4 sheet film. With no viewfinder and no shutter its a Universe away from shooting with a film camera and an eternity away from shooting with a digital camera. A Pinhole Camera or Camera Obscura is nothing more than a light sealed box with a very small hole used as a ‘lens’. The smaller the hole the sharper the image but the longer the exposure needed.
The first surviving mention of the principles behind the pinhole camera belongs to Mozi (470 to 390 BCE), a Chinese philosopher and the founder of Mohism. Mozi referred to this device as a “collecting plate” or “locked treasure room.”
