copper metal surface patina green texture aged
Prompt
Photorealistic macro close-up of an aged copper metal surface with natural green verdigris patina, shown as a small weathered circular disc leaning on a rough neutral stone surface, no markings or readable text. Emphasize pitted corrosion, oxidized blue-green speckles, dull brown copper undertones, scratched matte texture, and uneven worn edges. Composition places the disc slightly left of center with the rim visible and a softly blurred dark industrial background, creating a quiet archival texture-study mood. Color palette of muted teal, oxidized green, tarnished copper, charcoal gray, and earthy beige. Natural diffused side light reveals fine surface relief without glare, shot on a macro 100mm lens, f/3.2, shallow depth of field, realistic grain.
