A recent issue of Popular Photography describes a setup for back lighting natural subjects with a pure white background. The method looked rather complicated for field use so I have been searching for an easily portable alternative. I have been experimenting with using my iPad (version 1) with the free app. FreeLight. It provides a quite uniform white, or other color, light field. There are two problems with using the iPad directly; the screen is reflective, and the screen pixels are discernible in close macro photos. My initial solution is to use a semi-transparent sheet of white paper. This works fine for reducing reflections and renders the pixels invisible, but reduces the intensity of the light by one or two stops. Attached is an initial photo attempt, a bug on a willow leaf. (Canon 5D II with 100mm Canon macro, f:6.3, ISO 800, 1/60 s. Backlit plus side-lighting from an open window). I am interested in comments on my method and suggestions of other alternatives.
