### Full prompt
```text
A documentary-style close-up inspection photograph of a weathered [reinforced concrete bridge pier] outdoors, exhibiting severe alkali-silica reaction (ASR) damage.

- Composition: The structure fills most of the frame from a slight perspective angle showing both the front face and left edge, with a horizontal construction joint near the base.
- Damage Details: Rough, aged, and stained gray concrete covered in a dense network of irregular polygonal map cracking with approximately [18] distinct crack cells. Crack fissures show pale white gel exudation and chalky efflorescence along edges, with vertical whitish and brownish mineral drainage streaks running downward from intersections. Darker damp moisture staining along the lower section, plus faint moss or algae growth near the perimeter.
- Environment: Set in an [overcast riverside drainage channel] setting with sparse winter vegetation, scattered rocks at the bottom right, and a calm strip of water along the far right edge.
- Style & Lighting: Neutral diffused daylight, sharp focus on aggregate and crack textures, civil engineering report aesthetic. No people, tools, watermarks, or annotations.
