Depth of field calculator.
I wonder why I never thought about this kind of software before today. A depth of field calculator for smartphones, the tool that you always carry in your pocket or in your camera bag. It’s obvious when you search for such tool that you find a lot of them. However, I’ve tried and I found out that myDOF is the most well featured. The program is free and includes a wide range of digital cameras presets and is fast and easy to use. A must have !
