Wilson Bentley is one of the first known snowflake photographers. He was fascinated by snow from an early age and worked tirelessly to capture detailed images of each unique snow crystal. His process involved catching each snowflake on black fabric and and then using a microscope and bellows camera to photograph them.
You may have heard that every snowflake is unique, but to really get a sense of that you've got to dig down to the microscopic level. That's exactly what the folks over at the Beltsville Agricultural Research Center in Maryland did with a Low Temperature Scanning Electron Microscope (or LT-SEM). The result? A look at the structure of snow crystals in all shapes and configurations. Some of them even look like alien architecture from a distant world. Check it out in the gallery below — the shapes just get crazier and crazier. After all, we're all not tired of snow just yet, right?
