Simple. Just remember to take the lenscap off your lens BEFORE you start drilling. :) If you buy a pinhole someone else made it'll probably be more precisely round and you'll know the exact diameter and can therefore calculate the f/stop and figure out exposure. If you make your own using a pin and an alumin(i)um pie pan, you have to experiment with exposure. But, then you made your own! -Aaron At 07:22 PM 2/20/2006, you wrote: >Thanks!
