I think I either need an actual macro lens (this was with a stack of macro filters) or different snow (it was falling in giant clusters, hard to isolate a single flake) or a darker background...or maybe snowflake photography is never going to be one of my strengths...
@clairvaux Thanks! Actually, it's the back of one of my fingerless mitts. I just had a look through your macro photography and wow! You have some really awesome shots there!
