With the help of a powerful 3D microscope, the Hawaii-based photographer Gary Greenberg shoots stunning macro images of grains of sand, dissecting the seemingly uniform material into otherworldly crystals. The microscope, which the artist himself invented after earning a Ph.D. in biomedical research, magnifies the microscopic to 300 times their original size; the machine also affords the resultant images an astounding depth of field, capturing the most subtle curves and structures of the minuscule grains of sand.
Greenberg derives pleasure from the unpredictability of his process; each beach has a diverse history and therefore produces unique sand. In Maui alone, the grain shapes range from cylinders to spirals; they can be vividly colored or more muted. In the same handful of sand, we might find a tiny shell beside a microscopic mineral section that resembles an eaten corn cob.
