2. **Deep shadows** — low sun angle casting long shadows into the canyon, revealing depth
3. **Massive scale** — vast canyon expanse with distant rim visible
4. **Golden hour light** — warm directional light raking across rock faces
5. **Atmospheric perspective** — haze and colour shift across the canyon's depth

## Brain Config

## What Success Looks Like
- Red/orange rock strata clearly visible with distinct layering
- Strong directional golden hour lighting with deep shadows in canyon recesses
- Atmospheric perspective creating depth across the canyon (near faces saturated, far walls hazy)
- Sense of enormous scale and geological depth
- Warm colour temperature consistent with low sun angle
