Bluestone Pond, the developers of iOS app "SetMyCamera" provided me a review copy of SetMyCamera Pro. This is an excellent Universal iOS app compatible with iPhone, iPod, iPad and iPad Mini. For a photographer, this application helps remove the guessing game or trial-and-error of what camera settings are needed to get the depth of field you want, the field of view you want, conversion distance calculator, and many other useful tools. The "Pro" version of the application also includes Remote Control Trigger for specific cameras, but requires an IR accessory that plugs into the headset port of your device. The app has an excellent Info section that explains all of the features of the app and how to use them. And all of this is information is embedded inside the application so you don't have to be in a location with a data connection to use it.
