A vernal pool in the woods of Rachel Carson National Wildlife Refuge, fallen oak leaves of several shades of warm brown, and just cold enough to freeze the surface into crazy patterns which catch the light in interesting ways. It must be that the patterns are caused by variations in surface tension (or perhaps even water temperature) due to the barely submerged leaves. I am sure there is science behind it, but the effect is, at least to me, captivating, especially when it is contrasted with the shapes of the leaves themselves.
This is a long zoom shot, at 520mm equivalent field of view, to provide just enough isolation to emphasize the patterns, and just enough magnification to clearly delineate them. Canon SX40HS in Program with iContrast and –1/3EV exposure compensation. f5.8 @ 1/160th @ ISO 500. It is so nice to be able to leave the Canon in Program, with auto ISO, and just shoot, with confidence that the results will be excellent no matter how high the ISO goes to maintain decent shutter speed for handholding long zoom shots! If I had had to dance around ISO and shutter speed considerations for this shot, it would have difficult to impossible, and the result would not, certainly, have been either so sharp or so vibrant.
