# Architectural & Interior Cinematography

## Core Philosophy

Architectural cinematography treats space as a living entity with volume, memory, and purpose. The camera reveals what the architect intended and what time has added. Geometry is the hero; light is the narrator; material is the texture of the story.

## Perspective and Vertical Control

### The Vertical Imperative
- **True verticals are non-negotiable**: Unless the shot is specifically about distortion, converging verticals read as error, not style.
- **Shift lenses (T/S)**: The architectural standard. 24mm T/S for full frame, 17mm for cropped. Shift up to 12mm to correct while keeping camera level.
- **Keystone correction**: Digital correction acceptable when shift insufficient, but reduces resolution and changes spatial relationship at frame edges.
- **High vs. low camera**: High camera (6-10 feet) reveals plan and spatial flow. Low camera (2-3 feet) emphasizes ceiling and volume. Never default to eye-height without intent.

### Horizontal Geometry
- **Leading lines**: Use corridors, eaves, window mullions, and floor joints to drive the eye. Lines must resolve purposefully—into a door, a window, a feature.
- **Symmetry and break**: Centered symmetry is powerful but static. The intentional break (a chair pulled out, a light left on) creates narrative.
- **Corner avoidance**: Shooting directly into a corner flattens space. Offset by 15-30 degrees to show both planes.

### Scale Reference
- **Human figure**: The most reliable scale reference. A person in the frame immediately communicates ceiling height, door scale, and spatial generosity.
- **Furniture as metric**: Standard chair seat height (18"), door height (80"), countertop (36"). These known quantities anchor the unfamiliar space.
- **Vanishing point control**: In one-point perspective, the vanishing point should not sit on the edge of frame. Center it or place it purposefully in the lower or upper third.

## Ambient Occlusion and Spatial Depth

### Natural Light as Primary Source
- **Window dominance**: Interior cinematography lives or dies by window light management. The ratio between window and interior is the first decision.
- **Time of day by orientation**:
  - **East facing**: Morning warmth, direct beam, long shadows through space. Active, awakening.
  - **South facing**: Harsh midday, high contrast, requires significant fill or ND on windows.
  - **West facing**: Golden hour warmth, dramatic late light, long shadows. Emotional, nostalgic.
  - **North facing**: Soft, even, consistent. The artist's light. Minimal change throughout day.

### Artificial Light Integration
- **Practical sources**: Every visible light must earn its place. Lamps, pendants, and sconces create depth through warm pools of light.
- **Color temperature layering**: Warm tungsten (2700-3200K) practicals against cooler daylight (5600K) creates dimensional color contrast.
- **Motivated fill**: Add fill only where a plausible source exists. Unmotivated flat light destroys architectural volume.

### Shadows as Volume
- **Shadow edge sharpness**: Sharp shadows read as direct, hard, modern. Soft shadows read as diffused, gentle, traditional.
- **Shadow direction**: The angle of shadow reveals time of day, light source position, and spatial depth.
- **The occlusion gradient**: Where light wraps around a column or overhang, the gradual darkening creates roundness. Preserve this in exposure.

## Material Rendering

### Surface Response by Type

| Material | Key Visual Property | Lighting Requirement |
|----------|---------------------|---------------------|
| Polished concrete | Reflectivity, subtle sheen, aggregate texture | Raking light for texture; soft for sheen |
| Natural stone | Veining, pitting, crystalline sparkle | Side light reveals texture; fill preserves detail |
| Wood grain | Figure, patina, specular response along grain | Angled light across grain; never flat frontal |
| Glass / curtain wall | Transparency, reflection, green edge tint | Manage reflections; show what is beyond |
| Metal / steel | Specular highlight, brushed directionality | Composed reflection; edge light for profile |
| Plaster / lime | Chalkiness, subtle color variation, imperfection | Very soft, enveloping light |
| Fabric / upholstery | Pile direction, seam detail, tension | Soft side light; no harsh texture exaggeration |

### Material Combinations
- **Contrast principle**: Rough against smooth, matte against glossy, warm against cool. Architecture reads through material dialogue.
- **Patina and age**: The stain on stone, the wear on a stair nosing, the oxidation on copper—these are temporal evidence. Never eliminate unless the story demands newness.

## Real Estate and Showcase Protocol

### The Walkthrough Sequence
- **Establishing exterior**: Context, scale, approach. Drone or elevated position.
- **Entry and threshold**: The moment of transition. Threshold light difference is narrative.
- **Reception / living**: The primary social space. Wide, welcoming, filled with best light.
- **Kitchen**: Work triangle, appliance quality, island as stage. Detail on faucet, hardware, material joint.
- **Private spaces**: Bedrooms at rest. Beds made with intention, not hotel perfection. Window light primary.
- **Bathrooms**: Reflection control. Mirror must not show crew or equipment. Water features running.
- **Outdoor space**: Extension of interior. Connection through window frames and door openings.

### Luxury vs. Affordable Language
- **Luxury**: Negative space, fewer objects, each object considered. Light is sculptural. Camera movement is slow, deliberate.
- **Affordable / family**: Warmth, activity, life signs. Light is generous and even. Camera movement is energetic, approachable.

## Movement and Camera Path

### Static Frames
- **The locked-off reveal**: Hold on empty space; a figure enters. Architecture as stage.
- **Time-lapse shadow play**: Locked off for hours, compressed to seconds. The sun writes on the walls.
- **Window frame as picture**: Interior looking out. The room frames the world.

### Motivated Motion
- **Dolly along the wall**: Reveals surface material over time. Speed: 1-2 feet per second for contemplation.
- **Crane rise**: From interior to exterior perspective. The roof becomes a plane in the landscape.
- **Tracking through threshold**: Door frame passes through foreground. The compression of the frame edge emphasizes transition.

## Exterior and Context

### The Building in Place
- **Contextual relationship**: The building against sky, against street, against landscape. Scale is established by what surrounds.
- **Weather as character**: Architecture in rain reveals material behavior. In fog, form dissolves into mass. In snow, purity and contrast.
- **The twilight transition (blue hour)**: Interior warmth against exterior blue. The building becomes a lantern. The most valuable 20 minutes of the day.
- **Night as object**: Architecture as illuminated sculpture. Conceal the sources; reveal the form.

## Technical Discipline

### Focus and Depth
- **Hyperfocal strategy**: For wide establishing shots, focus at hyperfocal distance to maximize sharp range.
- **Tilt-shift focus plane**: Align the focus plane to the primary architectural plane (floor, facade) for extended sharpness without closing aperture excessively.
- **Deep focus aesthetic**: f/8-f/11 on wide lens. Everything sharp. The architectural standard.

### Lens Selection
- **Ultra-wide (14-20mm)**: Spatial exaggeration, dramatic volume, careful human placement to avoid distortion.
- **Wide (24-35mm)**: The honest room. Standard architectural workhorse.
- **Normal (50mm)**: Compression of spatial layers. The view as the eye would prefer it.
- **Telephoto (85-135mm)**: Detail extraction, facade patterns, abstracted material close-up.

## Quick Reference: Architecture Shot Checklist

Before approving any architectural frame:

- [ ] Verticals are true or intentionally distorted with purpose stated
- [ ] Converging lines resolve to a meaningful point
- [ ] Material texture visible and accurately rendered
- [ ] Light source direction clear and motivated
- [ ] Windows managed: no blowout unless intentional; exterior visible where relevant
- [ ] Scale reference present or unnecessary by design
- [ ] Shadows create volume, not confusion
- [ ] Color temperature consistent or intentionally layered
- [ ] No crew, equipment, or unintended reflection visible
- [ ] The space tells a story about its purpose and inhabitants
