copper metal surface patina green texture aged
Prompt
Photorealistic macro still life of a small aged copper fastener or rivet lying on a dark gritty metal surface, covered in turquoise-green patina, oxidized speckles, and warm rust-brown wear. A second circular metal piece sits softly blurred behind it, creating depth and context without drawing focus. Low angled composition with the main round form slightly off center, tactile texture emphasized by fine dust and rough granules in the foreground. Soft directional natural light from the upper left, muted shadows, calm industrial mood. Color palette of verdigris green, tarnished copper, charcoal gray, and earthy brown. Shot on a 100mm macro lens, f/2.8, very shallow depth of field, realistic grain and crisp micro-detail.
