I was captivated by the contrast between the structure of the old stump and the fungus growing on the edge. I was using a 35mm lens at f/6.3 and I focused on one of the large cracks in the wood, thinking that the depth of field would cover the fungus, too. I wanted both to be crisp. But no, the depth of field was not quite sufficient to make me happy. Of course, I'll gain additional 'depth' due to the small size of the posted file, but that's cheating, right? No worries, I'll return to the scene again later to refine the result. It's kind of like spiraling in to the find the optimum result.
