First a brief definition of DoF -
Basically, depth of field refers to the section of a photograph, from the nearest to the furthermost points from the camera, which appears to be in sharp focus.
John Shaw’s Landscape Photography, John Shaw, 1994
I came across DoFMaster website by accident. Of course I knew what DoF is. I’ve even used the marks on the lenses (in good old film days) to be able to determine what my DoF would be at any given aperture. Unfortunately those days are gone. Modern lenses do not provide DoF marks any more. Bummer!
DOFMaster to the rescue. This software (available for Windows, PalmOS, iPhone, iPod Touch and on-line) allows you to calculate the DoF for any given focal length and aperture. Quite useful. What I especially find very attractive about this software is the fact that you can access it on the road with your Palm, iPhone or iPod Touch. For those of you who do not have any of these gadgets there is a printed chart available.
