April 27, 2008 was celebrated as Worldwide Pinhole Photography day. Since 2001, the last sunday in April is dedicated for this celebration. People in the digital world may not be aware of Pinhole Photography. Perhaps some will vaguely remember learning in school science textbooks.

Pinhole photography is the oldest form of taking pictures using a simple box without a lense. The box has a tiny hole and a sheet of film pinned inside opposite the hole. The results depend on the pinhole size and the distance between the pinhole and the film. From trial and error you can achieve a fairly good picture.

Corbis - the stock photography company, has created a few PDF templates for creating pinhole cameras which can be printed and assembled. The templates are available to download free online at http://www.corbis.readymech.com/en
