PocketDOF is a depth of field calculator intended for photographers.

It is currently available for Windows Mobile and Android phones/PDA.

PocketDOF allows you to calculate precise information regarding the hyperfocal distance and the area of sharpness (depth of field), given the confusion circle, the focal and aperture of the lens and the distance of the subject.

It also allows you to reverse the calculation of DOF, that is calculate the focus distance and minimal aperture given the focal and depth-of-field required.

 

PocketDOF for Windows Mobile works both in english and french
