Re: infrared pinhole

Gord -

Don't forget to give pinhole sieve a try
(http://glsmyth.com/Pinhole/Images/PinholeImages.htm). It is faster than
pinhole (similar to zone plate) and gives a very ethereal effect.

It sounds like you've got a lot of it, so have fun. I've got a roll of 12"
wide film and am planning to play around with it also.

Cheers -
