ShutterSpeed is a simple Android application I wrote this weekend. The application itself is not terribly useful nor interesting, but it shows how to create an Android application that uses a few advanced features like orientation-based layouts, styles, themes, etc.
ShutterSpeed lets you compute the correct exposure for the ISO and aperture of your choice, given another another duration for different settings. For instance, my digital camera cannot tell me what the exposure should be at ISO 100 and f/16 for a street scene at night. With ShutterSpeed, I can just change my settings to ISO 800 and f/2.8 and get an exposure reading from the camera. The application then tells me what the equivalent is for the settings I really want.
