See? It's true, no 2 Snowflakes are alike! Too bad the middle one had a few points broken off! I like this photo because it shows 2 of the different types of snowflakes. The shape a snowflake has is determined by the air temperature in the clouds. The snowflakes on the top right and left are dendrite
. The middle one is a sector plate
. Plate snowflakes form in temperatures of 10 to 14 degrees. The more complicated dendrites form at 3 - 10 degrees. It is possible to have more than one type of snowflake depending on what part (air temperature) of the cloud it formed in.
A good website to learn more about snowflake types is: Types of snowflakes
This photo was taken with a 105mm macro lens and a flash. I catch myself holding my breath so I don't melt them or blow them away!
