DOF is a program for photographers that computes the depth of field for a lens given its focal length, f stop, focus distance and the desired resolution at the film plane. It reports the near and far focus limits as well as the hyperfocal distance. For more information, see the readme.txt and help files.

To install DOF, first establish a connection between your desktop PC and your Pocket PC, then run DOF.exe on your desktop PC and follow the on-screen instructions.
