Digital Pinhole Camera
Lancor, Rachael; Lancor, Brian
Physics Teacher, v52 n9 p546-547 Dec 2014
In this article we describe how the classic pinhole camera demonstration can be adapted for use with digital cameras. Students can easily explore the effects of the size of the pinhole and its distance from the sensor on exposure time, magnification, and image quality. Instructions for constructing a digital pinhole camera and our method for calculating the effective focal length of the "lens" are included.
