Kenneth Libbrecht developed a special super-high-resolution photomicroscopy apparatus designed especially for snow crystal photography. His collaborator, photographer Patricia Rasmussen, used this technique to capture stunning pictures of Wisconsin snowflakes.
Libbrecht writes on the Web site, "Snowflakes are temporary works of art. After just a few short minutes on the ground, a fallen snowflake will lose its ornate structure, its unique pattern that will never again be repeated. Photography allows us to preserve a few of these minute masterpieces and to examine their form up close."
Take a look at the lovely photographs of these fleeting wonders.
