Hi all,
I just work out a calculator with PHP and would like to share it with you
all. Hope it also help the newbie to the WDDP.

The calculator can calculate the optimum pinhole size and f/stop with a
known focal length or the f/stop with a known focal legnth and pinhole size.

Please feel free to test, use and comments.

Enjoy it!
