I've never shot snowflakes before, and decided to give it a whack today, during our 8th snow in just over a month. I had decided to shoot them this morning around 8:30am when the flakes falling were still flakes.
By the time I got out later in the morning, the air had warmed up and the flakes were clumps of ice spikes instead. I snagged a few shots of the clumpy spiky stuff. I'll try to get something more snowflakey another time.
As an aside, pretty much everything I know about shooting snowflakes and other crystals (as well as the methods I use to shoot many other subjects in macro/micro), I learned by reading about Ken Liebbrecht's work at Caltech. So, thanks Ken, if you ever read this!
Send me your suggestions for something tiny that you'd like to see big.
