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. http://www.zeroimage.com/try_php/fstopcal4.php Please feel free to test, use and comments. Enjoy it! Zernike
