BTW - it may be that the glass was a little dirty, but you might need to clean your *ist-D sensor. Any irregularity or dirt on the sensor will show up like crazy with this kind of shooting. I finally resigned myself to swabbing the sensor (using the Eclipse cleaning solution and specially designed swabs...)
Good luck!

Subject: re: Website Update - 2004/05 Snowcrystals
After reading Mark Cassino's recent posting explaining how he takes his amazing snowflake photographs I've been itching to give it a try... so of course we get a thaw and no snow falls !!
Today the snow returned and the temperatures were moderate so as soon as I got home from work I hooked up my old screwmount bellows to the *ist-DS, reverse mounted a SMC 55mm F2 on an ST 105mm F2.8, and headed out to the garage. I mounted the camera on a tripod with my latest ebay purchase, a Soligor macro focussing rail, and collected some flakes on a sheet of glass. I put a flashlight in a garbage can to provide some back lighting then balanced the glass on the garbage can, and adjusted the tripod to shoot down through the glass.
Here's my results: http://ist.uwaterloo.ca/~fwwidall/Snowflakes/
Mark's images are vastly superior but as an early attempt I'm quite pleased with what I got. I think I need to reduce my magnification, and ensure the lens and glass are parallel. Depth of field is approx. zero !
Please don't report me about #5, it wasn't my fault. He just got overheated in his excitment at being photographed :)
