Incredibly Colourful Magnified Grains of Sand

Viewed at an astounding magnification of over 250 times, tiny grains of sand are surprisingly colorful and extremely unique. Each piece is either a fragment of crystals, spiral fragments of shells or crumbs of volcanic rock.

To see these incredible images, Dr. Gary Greenberg goes through a painstakingly lengthy process. First he takes many photos from different points of focus. Then, he combines them using software to produce one spectacular image.

“It is incredible to think when you are walking on the beach you are standing on these tiny treasures,” says Greenberg.”
