Plate XIX of "Studies among the Snow Crystals ... " by Wilson Bentley 1902
Wikipedia commons - Public domainI have been doing some research for an etching and wanted to try a snowflake. In looking for images, I came across The Snowflake Man. Wilson Bentley, a Vermont farmer, was obsessed with the structure of snow crystals and learned to photograph individual flakes, through a microscope and bellows camera, creating an amazing series of hundreds of separate images.
No two snow flakes are ever alike. Wilson Bentley indeed proved this back in the late 1800s.
