A nebula in space? The surface of a faraway planet? A fantastic sci-fi illustration? Or just microscopic goo? It's just ice, like the rest of these fantastic photos by Michael Wagner.
Here's he how he takes them:
This set was created by back lighting blocks of ice with battery powered LED holiday lights. For equipment, I used a Canon 60D with a Canon EF-S 60mm f/2.8 Macro USM, and Canon EF 100mm f/2.8L IS USM macro lens. Each picture is a combination of 15-40 shots that have been focus stacked to capture a larger depth of field.
