FREE DCE Free DCE does the hard job of noise reducing and automatic balance control for you. And it is free!

The program works best if you have bad light condition (indoor, shadows etc..) and your image is somehow off. So if some of your images are already fine, you won't see much difference. DCE makes very delicate changes.

Depth of Field (DOF) Calculator Software by Don Risi
The DOF calculator I use is only available for Android, and is available on the Google Play Store.
He​re is a link to another excellent DOF calculator that is available for both Android and iPhone, as well as an online version.  It gives the exact same results.
