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.
Square 1:1 frame. A strip of oak bark peeled back from a fallen log shows its pale inner face engraved with the tunnels of bark beetles: one straight mother gallery runs up the centre and nine fine larval galleries branch away from it in widening, comb-like curves. A single small brown beetle sits at the bottom end of the mother gallery, and a thread of wood dust lies along one tunnel. The gallery pattern fills the frame, the centre tunnel is sharpest and the edges fall into soft blur, with the dark rough outer bark curling at the left edge.
Pale cream wood contrasts with the dark tunnels, rust-brown wood dust and the beetle's glossy chestnut shell, and fine fibre and tunnel edges stay crisp inside the focus plane.
