copper metal surface patina green texture aged
Prompt
Photorealistic macro study of an irregular aged copper fragment resting on a matte charcoal-black surface, filling most of the frame as an abstract background texture. The metal is heavily oxidized with powdery turquoise-green verdigris, dusty salmon-brown corrosion, small pits, raised crusty nodules, scratches, and mineral-like roughness. Compose from a slightly elevated top-down angle with the object centered and its uneven silhouette clearly visible against the dark negative space. Use soft directional light from the upper right, creating gentle highlights on the patina and a muted shadow along the lower left. Mood is quiet, archaeological, tactile, and weathered. Color palette of teal green, oxidized copper, clay beige, charcoal, and subtle yellow ochre. Shot on a 90mm macro lens, f/5.6, natural detail, realistic texture.
