Pinhole Photography

Creating photos without a lens

Pinhole cameras and solargraphs use a tiny hole and photo paper to take long exposure pictures. The former can be exposed for a long (seconds-minues depending on brightness) time which can be developed and processed later. The solargraph image is burned into the film over a very long time (days) and requires no development chemicals but will fade with additional light exposure. Once exposed and developed, scanning the negative makes it easy to to invert the negative and correct for some minor exposure issues.

The use of the pinhole camera has lasted over millennia, from sightings back as far as 500 B.C. Another useful pinhole apparatus is a woven straw hat, which during a Solar Eclipse, will make hundreds of crescent Sols in its shadow.
