Simple Android application

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, a simple Android application

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.

The application is licensed under the Apache 2.0 License and is available as binaries or source code. This application requires the Android SDK 0.9.

    Just for the fun of it, what about adding a little GUI galore by having the diaphragm closing/opening according to the selected aperture? :-p

    Actually, it’s been in the works since I wrote the app. I’m just having trouble making it look good and realistic (using straight blades is easy, curved blades is more difficult.)

    Haha! I should have guessed that you WOULD have done it.

    Thanks for this great application but does not work on my tattoo. You could modify it to the screen of the htc tattoo? Thank you very much
