A single subject can be the source of multiple images. A single head of common teasel is quite interesting when considered carefully.
This image is a focus stacked composite of 20 individual images taken at 1/8 inch intervals through the depth of the subject. See the previous post, Focus Stacking to Increase Effective Depth of Field, for more information about focus stacking.
The teasel was lit by a single flash unit directly above it and was photographed with a Nikon D800 with an AF Micro-NIKKOR 200mm f/4D IF-ED lens. The images were compiled with Zerene Stacker software.
