Water crystals photography

I was going through the Photo-Blogs of one of my customers in Japan, and I saw some snaps of snowflakes which he had clicked. I was amazed to say the least as I had always thought that snowflakes were microscopic and needed microscopes to view and photograph. Apparently, I was mistaken. So, once I returned home, I tried to photograph the ice crystals which had condensed in and around my freezer. Though they were not of the hexagonal fractal types, which we normally associate snowflakes with, I got some good shots. I used my reverse adapter along with a Nikon Autoextension ring to really increase the magnification.
