Snowflakes

I have been trying to capture snowflakes but it is a very hard task. The best spot to see them is on the attic windows as they are at an angle and stick better. It was -6 degrees today so they stayed long enough to photograph before the next flakes fell on them and destroyed them. Bending backwards so I was approximately parallel to the glass while trying to get the neighbour's chimney in the background as a dark contrast was quite a challenge. I made a collage to show the many different shapes but they are probably a bit small. The extra shows a single shot.
It snowed the whole day so watching tennis and skiing was a good way to pass the day.
