Falling attitudes of snowflakes were smultaneously photographed by two video cameras from horizontal and vertical directions, and these images were analyzed by an image processor and personal computer. The attitude of each snowflake was measured every 1/30 second frog! its two images. It is generally found that snowflake images from the top are larger than the ones from the side and some of snowflakes rotate during fall.
