Ultra-realistic 3D still life rendering, eye-level slightly low shooting angle, medium depth of field, centrally composed subject, 1:1 square frame, solid dark charcoal black uncluttered background, dark gray matte supporting surface; the main subject is a vintage Chinese solid wood abacus, with a deep reddish-brown rosewood frame featuring fine natural vertical wood grain, distressed brass corner protectors installed at all four corners, fixed with rivets, showing vintage texture of natural oxidation and minor use scratches; two horizontal wooden beams are set inside the frame, with small brass fasteners at both ends, 11 evenly spaced antique bronze metal rods run through the upper and lower frame, each rod strung with matching deep reddish-brown flat round solid wood beads with smooth surfaces and warm wood luster; one bead on each rod in the upper section is pressed against the top beam above, one bead on each rod in the middle section is pressed against the middle beam between the two horizontal beams, five beads on each rod in the lower section are stacked at the bottom close to the lower frame; soft side lighting illuminates the subject from the front left, natural soft shadows, a faint soft contact shadow cast on the surface under the abacus, no extra decorative elements, overall calm and vintage atmosphere.
