Perform professional e-commerce product photography-grade retouching, 3D rendering, accurately restoring the product's colors and packaging materials (such as the transparency of glass, matte plastic, metallic sheen). Output a realistic, clear, refined product image on a white background. "Lock the original scale/graduation area, adjust only materials and lighting." If the numbers change after generation, paste the original scale markings back onto the image.
[Red Metal Retouching]
While keeping the original red hue, present a delicate, uniform anodized metal texture. Clean up surface noise, stains, color casts, and compression artifacts, while retaining appropriate realistic metal texture. Use soft gradient highlights to express flat surfaces, sides, and chamfers, making the edges clean and crisp with clear thickness. Avoid over-saturation, a plastic feel, mirror-chrome appearance, and large areas of blown-out white reflections. Preserve the scale numbers, graduations, units, and their positions exactly as they are, keeping the font and tick marks consistent—do not rewrite, add, or guess numbers. Keep the round hole edges clear, with natural light and shadow and depth inside the hole. The silver washer and screw should show realistic metallic luster, the black knob should retain a fine matte texture, and the threads should be clear but not over-sharpened. Use professional studio large-area soft lighting, with soft key light and even fill light, unifying the light direction and color temperature across all parts. The background is clean pure white RGB 255,255,255, with only a slight, natural contact shadow beneath the product to enhance the sense of grounding. Remove cutout white edges, gray edges, jaggies, and floating appearance.
Output a square high-resolution image, recommended 3000 × 3000 pixels. The overall effect should resemble real commercial product photography—clear, restrained, and textured.
