Prompt
A real photograph, macro photograph at 1:1 life-size magnification on a 100mm macro lens wide open near f/3.2, so the focus plane is razor-thin and dissolves millimetres away into soft blur. One dominant soft diffused light from above and slightly to one side models gentle relief, revealing true surface micro-texture, fine stippling and small hairs with clean, controlled specular highlights. Real tactile detail at believable scale, low-noise sensor clarity, and a crisp neutral colour finish with delicate tonal separation inside the sharp plane.
Wide 16:9 frame. At low water a small shore crab with a plain brown-green shell, two claws and eight walking legs shelters in a narrow gap between two rocks at the edge of the same granite tide pool: a rounded basin of dark granite with a barnacle-crusted left rim, a pale green weed shelf along the back and a bed of pebbles and shell fragments, only its eyes and claws showing above the damp rock, a film of water glinting on the stone and one barnacle cluster beside it. Soft morning side light. No people, hands, text or objects made by people appear anywhere.
