Spent nearly two hours standing in the woods photographing a single dogwood tree - just four blossoms on that tree to be more precise. Every angle, every distance, every DOF, several lenses - I guess that's what they mean when referring to working a subject.
Used my "plamp" (plant clamp made by Wimberly) to good effect to keep the subject more or less in the right position (and sort of anchored against a light breeze).
