It can be changed, operated, and even printed out to make a field serviceable DOF calculator. This may be of interest to people who have cameras without DOF indications, or to students who want to understand DOF better.

I made a set of discs for my LF lenses a couple of years ago using this software but forgot where I go it from - thanks for reminding me!

Works very well.
