Snowflake photography

While thinking about Christmassy photos this evening, I wondered how easy it would be to photograph snowflakes. I quickly came across, which has dozens of utterly beautiful images:

Snowflake 1 Snowflake 2

How easy is it to photograph them? Not very. The above shots were taken in the field, at -15 degrees celcius, with a purpose-built photomicroscope and coloured backlights. Aren’t they gorgeous, though? The site is full of the science behind snowflakes, and it’s worth exploring – they managed to grow a 2.5cm snowflake. I really want the book.
