polished stone surface dark granite smooth
Prompt
Photorealistic macro background of a smooth polished dark granite stone surface filling the entire frame, with fine natural mineral speckles in charcoal black, deep olive gray, muted bronze, and subtle cream flecks. The slab appears clean and commercial, gently reflective with a satin-gloss sheen, showing organic crystalline texture without cracks or distracting objects. Soft diffused studio light from the upper left creates delicate highlights and shallow tonal gradients, while the mood remains calm, minimal, and premium. Compose as a flat lay texture with edge-to-edge coverage, no visible labels or measuring tools, suitable as a neutral background. Shot on a 100mm macro lens, f/5.6, high detail, natural color accuracy, crisp but not oversharpened.
