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. In soft backlight a length of green bamboo stem sliced lengthwise lies on the bench showing the hollow tube interior divided by a solid partition wall at the node, the pale inner lining and the fibrous wall thickness along the cut edge, a short uncut section beside it, seen from slightly above and framed wide. No people, hands, text, numbers, labels or rulers appear. The object always sits on the same plain pale grey bench with a soft grey seamless background.
