I shot this before I converted to digital imaging when my method was to normally take three shots; one at metered exposure and another at 1 ev below and one at 1 ev above. I could always compensate for camera inconsistencies and when I finally moved to digital, the underexposed images gave me just what I needed for a full tonal pallet.
This photo represents about 2 inches of space on an old wooden gate. I hope to present the full view later. Ah, the beauty of macro photography!
