Nikon Small World

Krebs is a photographer specializing in nature and wildlife subjects. He chose to submit this image because of the geometric shapes and symmetry of the growing diatoms, together with the elaborate pattern and texture of the red-hued alga to which it was attached. Rather than showing a diatom as a single inanimate frustule, as is often the case, this image depicts living specimens growing attached to the highly textured Polysiphonia alga.

His image was captured using differential interference contrast. In order to portray the subject with sufficient depth-of-field a series of separate images made at different focal planes was combined to obtain the three-dimensional image.
