+# 04 — Prompt Guide (Interior / Carpet Photography)
+
+## The core pattern
+
+All image prompts follow this structure:
+
+```
+{camera angle} {lens} {subject description},
+{foreground detail} sharp in foreground, {background} receding into bokeh,
+{lighting description}, {style tag}, no people, ultra-realistic {type} photography
+```
+
+## Why this works
+
+FLUX.1 Schnell uses T5-XXL as the primary text encoder (6GB model) which
+understands natural language photography concepts deeply. Specifying lens
+focal length, depth of field, and spatial relationships produces images with
+correct depth, perspective, and scene geometry.
+
+SDXL models lack this — their text encoders (CLIP-L/CLIP-G) top out at
+77 tokens and don't understand spatial concepts reliably.
+
+## Lens vocabulary
+
+| Lens | Effect | Use for |
+|---|---|---|
+| 24mm wide-angle | Strong perspective distortion, exaggerated depth | Corridors, lobbies, open spaces |
+| 35mm | Natural perspective, slight depth emphasis | Most interior shots |
+| 50mm prime | Near-natural perspective, shallow DoF | Close-ups, furniture, details |
+| macro | Extreme close-up, very shallow DoF | Carpet fiber detail, texture |
+
+## Camera position vocabulary
+
+- `low-angle` / `low 35mm angle` — camera near floor level, looking across surface
+- `floor level` — pressed to the floor, extreme low angle
+- `corner angle` — shot from room corner, wide coverage
+- `looking up` — camera below subject, looking upward
+- `looking down` — camera above, bird's-eye (avoid for carpet — looks flat)
+
+## Depth of field vocabulary
+
+- `shallow depth of field` — subject sharp, background blurred
+- `razor sharp in foreground ... receding into bokeh` — specific foreground/background split
+- `raking light` — light hitting surface at low angle, reveals texture
+- `vanishing point perspective` — strong linear convergence (corridors, offices)
+
+## Lighting vocabulary
+
+- `warm afternoon window light` — residential, golden hour feel
+- `raking natural light` — reveals carpet texture and pile height
+- `recessed ceiling lights creating depth` — commercial/corporate
+- `warm wall sconces` — hotel corridors
+- `crisp morning light` — bedrooms, bright and clean
+
+## Full prompt examples
+
+Carpet hero (residential):
+```
+low-angle 35mm lens perspective looking across thick plush cream carpet
+in an upstate New York living room, carpet fibers razor sharp in foreground,
+couch and coffee table receding into shallow bokeh background,
+warm afternoon window light raking across carpet texture,
+Finger Lakes farmhouse interior, no people,
+ultra-realistic architectural photography, 16:9
+```
+
+Hotel corridor:
+```
+low 24mm lens looking down a long hotel corridor from floor level,
+patterned burgundy carpet runner sharp in extreme foreground receding to vanishing point,
+warm wall sconces lining white walls, numbered doors converging in perspective,
+no people, ultra-realistic hospitality photography, 16:9
+```
+
+Hardwood floor:
+```
+low 24mm angle pressed to gleaming light oak hardwood floor,
+floor grain razor sharp in extreme foreground receding to hallway vanishing point,
+white walls, natural light streaming in, shallow depth of field,
+no people, ultra-realistic interior photography, 16:9
+```
+
+## What NOT to include
+
+- No people, no faces, no hands, no feet, no shoes/boots
+- No cleaning machines, vacuums, steam equipment, hoses
+- No text, logos, watermarks in the scene
+- No "before state" (dirty carpet, stains) — only clean result
+- No "wide shot" without camera angle qualifier — produces flat frontal views
+
+## Video motion prompts (Wan 2.2)
+
+For animating stills, describe the camera motion, not the scene content:
+
+```
+slow dolly forward across {subject}, gentle camera push toward the far wall,
+{lighting}, cinematic, smooth motion
+```
+
+Motion types:
+- `slow dolly forward` — push toward subject
+- `slow pan {direction}` — lateral camera rotation
+- `tracking shot moving forward` — camera travels through space
+- `rack focus` — lens focus shifts from foreground to background
+- `gentle push in` — subtle zoom/move toward subject
