Wim van Egmond’s image of Chaetoceros debilis, a colonial marine diatom, took top spot in the 2013 Nikon Small World competition. It was magnified by 250 times.
The particular species documented in his winning photomicrograph was captured from marine plankton in the North Sea.
Van Egmond employed an image stacking technique. Combining many images, he used differential interference contrast, to obtain a dark blue background that provides a stunning contrast with the yellow and brown shades of the diatom.
