Use DOFMaster to calculate the depth of field in your photographs. You'll be able to select the lens and f/stop combination that provides the zone of sharpness you need. Use it to calculate the hyperfocal distance for landscape photography.

DOFMaster calculates total depth of field, near focus limit, far focus limit, and hyperfocal distance.

Depth of field can be calculated for any film or digital camera. Select a pre-set format (e.g., Canon DSLR, 35mm film, compact digital, Super 16, etc.) or a custom circle of confusion.

F-stops range from f/1 to f/64, with 1/3, 1/2, and full stops. Focal lengths range from 3mm to 1200mm. Use feet, meters, inches, or centimeters for input and output.

I’m working at improving my photography. I wanted an aid to help me determine my photo depth of field and I’ve found it with this program. This program is very easy to use and because I can store it on my ipod touch, very easy to carry. I highly recommend it.

Needs a little work..


I would gladly rate this app much higher if it was as complete as the Dofmaster web site app. Come on guys!!!

needs work


This is a very simple app that could be better with some fixes. At least switch the keyboard to numbers when expecting numerical input. And there is a button to switch to hyperfocal distances - but no way to get back! Why not report everything on the same page? No button. Less work.
