You catch rare and unique natural shapes and patterns. The effort and 
technical ability applied is considerable.
All very well done, Mark.
Thanks!

Hi Jack -

I just catch the crystals on a cold piece of glass. I do it all outside in my 
unheated / detached garage. As long as the glass is a few degrees below 
freezing it works fine. I've lost many crystals by holding the glass too close 
and breathing on them - another Homer Simpson DOH! moment...

I don't mind disclosing all the info about taking the shots. A couple of years 
ago I put together a little presentation about the evolution of the process. In 
the early days it was quite difficult - I used a Spotmatic and stacked lenses 
with extension, manual flash, and used a Lotus 1-2-3 spreadsheet (DOS version) 
on a 486 laptop to calculate the subject to flash distance, taking into account 
the exposure increase factor that the extension called for. With film, the 
technical aspects of getting a good exposure was difficult. With digital, you 
take your best guess, do a test shot, adjust once or twice and you are there. 
These days, anyone who is smart enough to tie their shoe can be a technically 
competent photographer. That puts the emphasis on composition and other 
factors, which is where it should be. At my little workshops I have shown 
dozens of people exactly how to take the snow crystal shots.

The real chllenge with snow crystals is just being there. In my experience, 
it's rare to have a storm where good crystals fall for a significant period of 
time. You get waves where nice crystals fall for a while - maybe 15 to 30 
minutes-  and then you get crap for a long while, then a little window with 
nice crystals. Unless you have a 6th sense for these things, you just have to 
stand outside in the cold for hours on end and see what is falling. That's what 
I do. I think that managing to "be there" is the biggest hurdle to good 
photography. I'd a helluva photographer if I could get up early and catch the 
morning light.
