A real photograph made underwater, captured in a housed full-frame digital camera with a 28mm lens at f/5.6, moderate depth of field, fine grain, suspended particles and glistening wet texture over every surface. Diffuse cyan-filtered daylight from above falls through the water column, shading downward into teal-blue falloff with soft refracted patterns playing across forms. Cool aquatic tonal rendering drifts from pale surface aqua into deep blue-green shadow.
Wide 16:9 frame. Seen from just under the surface in the same pool, a small crab walks across the pebble bed near the bottom while a sea snail climbs the weed shelf at mid-depth, both small in frame, with soft sunlight shafts and a pale weed shelf behind them. No people, hands, text or objects made by people appear anywhere.
