Snowflakes
Inspired by the incredible snowflake photography of Mark Cassino
for the past few winters I've been trying my hand at capturing snowflake images.

My current setup consists of a El-Nikkor 50m F2.8 enlarging lens reverse mounted on a Pentax Auto Belllows, which is mounted on a Pentax K20D. All this is then mounted on a homemade wooden copy stand.

The temperature needs to be cold enough that the crystals don't melt while you're working with them, but not so cold you freeze !! I find temperatures around -5C to be a good compromise. You also need good snow, not too 'clumpy' and
not too icy. Happily here in southern Ontario I have lots of snow crystals to play with :)

There's a lot of different shapes the snow crystals can take.

Be sure to check out the rest of Kenneth G. Libbrecht's very informative website - everything you could possibly wish to know about snow crystals.

Ken Libbrecht presented a lecture called "The Secret Life of a Snowflake: An Up-Close Look at the Science and the Splendor of Nature's Frozen Art" at the Perimeter Institute in Waterloo, Ontario on Feb 1st, 2012.
