About Depth of field calculator

This is a simple Depth of field calculator optimized for the Nokia N900. The original script comes from this site but it was completely rewritten by me. You can check the site for more information about depth of field in general.

The script calculates the Depth of field for a given filmformat, focal length, f/No and object distance. The calculations can be done in meters and feet.

The page can be saved as a single file so you can run it locally.
