A real photograph in the environmental genre, captured on a full-frame digital sensor with a 35mm lens at f/8 for deep contextual sharpness front to back and fine natural grain. A single broad late-afternoon sun key from high camera-right slants downward, settling into soft lengthening shadows with gentle ground-bounce lift in the shade, finished in a warm natural grade with lifelike colour and clear airy midtones. Wide 16:9 frame. In raking afternoon light a mayfly nymph clings flat to a smooth riffle stone in fast shallow current, its three tail filaments streaming behind it and its flattened body pressed against the stone, clear fast water streaming over the pebbled bed around it, seen from the side at close-medium distance with the stone and current clearly readable. No people, hands, nets, fishing gear, text or captions appear; the whole animal, its behaviour and its freshwater habitat are all clearly visible.
