PinholeCalc is a handy little utility that can be used to find the f-stop, optimum focal length, optimum pinhole diameter, and common exposure times based on film speed of a pinhole camera. A field of view calculator is also included. This program should handle just about all mathematical aspects of building and using a pinhole camera. The art is up to you!
