Prompt
River stone surface patterned by lichen colonies, contemplative and earthy beside a slow stream. The rock shows fine-grain granitic speckle, matte patches of crustose lichen, and hairline fissures that map subtle geometry. Focus rests on a central lichen rosette with pore-level clarity while surrounding speckles dissolve through a measured depth of field that preserves the stone’s contour. Even illumination creates soft edge brightness across lichen lobes, gentle roll-off into the darker matrix, and a neutral-warm grade that balances greens and grays against a subdued background. The setting includes a faint reflection glint and a softened reed as understated context. Eye-level vantage, short-tele field of view, portrait crop with the rosette placed on a golden-section point to anchor asymmetry. Macro photograph tuned for tactile realism and quiet tonal balance suitable for long viewing.
