My repeatable brief for architecture hero shots. Same structure every render — the model stops inventing random skylines and starts lighting the space I actually described.

## Brief: Timber-frame lakeside library, reading room **1. Camera.** Eye-level 24mm, two-point perspective, camera height 1.6 m, positioned at the room's southwest corner. Foreground third: the edge of an oak reading table with a single open book, slightly out of focus. Verticals corrected — state "architectural photography, corrected verticals, no lens distortion" in the prompt. **2. Light.** Primary: low west sun through the floor-to-ceiling glazing, ~4200K, entering at 15° — long shadows raking across the board-formed concrete floor to reveal its texture. Secondary: soft bounce from the birch ceiling filling the shelf alcoves, two stops down. The light's job: make the glulam frame read as warm and dimensional against the cool floor. **3. Materials, ranked.** (1) Glulam spruce frame — matte, honey-toned, dominant rhythm of the image. (2) Board-formed concrete — raw, raking-light texture, grounding the base. (3) Blackened steel shelving — satin, recessive, thin lines that give scale. **4. Entourage.** One figure, seated, far end of the room, facing the lake, soft-focused. Exclude: additional people, birds, signage, any text, decorative clutter on tables. **5. Negative space.** Upper-left sky and lake view stay quiet — headline overlay lives there. --- **Consolidated prompt:** Architectural photography of a timber-frame lakeside library reading room, eye-level 24mm two-point perspective from the southwest corner, corrected verticals, oak table edge soft in foreground. Low west sunlight at 4200K rakes long shadows across board-formed concrete, revealing texture; honey-toned glulam spruce frame dominates, satin blackened-steel shelves recede. One distant seated figure facing the lake, soft focus. Calm negative space upper left over water and sky. No text, no logos, no birds, no clutter. Photorealistic, editorial architecture magazine quality. **Variant A — golden hour:** replace lighting sentence with: warm 3200K grazing sun, amber highlights on glulam, deep soft shadows. **Variant B — overcast diffuse:** flat north-light, 6000K, shadowless volume, materials read by tone not texture. **Variant C — blue hour:** 8000K dusk exterior, interior lit at 2700K from shelf lighting, glazing glows against the lake.
