# S-10 Shot Brief V1

## Status

- Document status: created for direct S-10 generation.
- Execution status: S-10 image accepted by user.
- Project: `在路上`.
- Unit: `s10`.
- Source shot: `S-10`.
- Segment / time: Section B / `0:32-1:05`.
- Trial role: second shot in the five-shot visual test package.
- Style anchor: B｜高位观察型 / 城市边缘纪录片感.

## Purpose

S-10 tests whether the accepted visual system can translate pressure from "system" into physical space without showing technology literally.

Core test sentence:

> 城市变成峡谷，人物变成底部小坐标。

This shot should not be a city promotion image. It should make the traveler feel small inside a cold steel / concrete structure.

- Style board: global palette and drift-control reference.
- Character assets: identity, clothing, backpack, boots, and upright walking posture reference.

## Shot Definition

Source table definition:

> Steel canyon / city pressure.

Expanded execution definition:

> A tiny middle-aged traveler walks through the bottom of a massive steel-concrete urban edge. Bridge columns, overpass shadows, cold walls, wet ground, and structural scale create a canyon feeling. The shot should make modern systems feel heavy without showing UI, screens, code, or futuristic technology.

## Required Visual Content

The shot must include:

- 16:9 horizontal frame;
- high-angle or distant observational composition;
- urban edge, massive overpass, bridge columns, or steel-concrete canyon;
- wet gray ground, puddles, cold concrete, steel beams, and small rust traces;
- tiny traveler at the bottom or edge of frame, about `1/10` to `1/6` of the frame;
- long dark traveler's coat, old backpack, old boots;
- upright walking posture, not hunched or collapsed;
- low-saturation documentary realism.

## Composition Rules

Required composition:

- the structure is larger than the person;
- the person is a moving coordinate, not the main hero;
- overhead pressure, side pressure, and forward length should all be visible;
- no centered hero pose;
- no face-first or portrait composition.

Recommended layout:

- overhead or high-observation angle looking down into a concrete / steel channel;
- person placed at lower third, lower edge, or side-bottom path;
- wet ground and vertical supports create geometric pressure.

## Character Rules

The traveler should be recognizable mainly through:

- black rectangular glasses only if visible, but face detail is not required;
- longer messy dark hair outline;
- longer dense beard / stubble only if the side view is readable;
- dark gray / dark khaki / coal-black long road-worn coat;
- old medium-volume backpack;
- old muddy boots;
- upright chest and straight walking spine.

Do not make him:

- hunched;
- collapsed;
- homeless-coded;
- drunk-coded;
- a fashion model;
- a heroic poster figure;
- a city explorer / travel blogger.

## Color And Light

Preferred:

- steel gray;
- concrete gray;
- wet blue-gray;
- coal black;
- dark khaki;
- small rust-brown traces.

Lighting:

- overcast;
- bridge shadow;
- cold reflected light from wet ground;
- no bright sun;
- no dramatic commercial rim light.

Avoid:

- neon blue / purple;
- cyberpunk glow;
- orange-blue blockbuster city grading;
- polished commercial skyline.

## Forbidden Drift

Reject if the image becomes:

- futuristic city;
- AI interface / code / screen / UI image;
- clean CBD promotion;
- glass-tower city advertisement;
- cyberpunk / neon / sci-fi;
- fashion street photo;
- heroic centered pose;
- portrait MV image;
- the traveler is bent, collapsed, or spiritually defeated;
- text, logo, UI, watermark, readable signage as main subject.

## Acceptance Criteria

S-10 passes only if:

1. The city edge feels oppressive.
2. The traveler is small enough.
3. The frame has a steel / concrete canyon feeling.
4. It reads as city edge, not prosperous city promotion.
5. There is no tech UI, code, screen, or sci-fi drift.
6. The traveler is walking naturally, not posing.
7. It can connect from "gravity downward" into "where is home".

## Next Action

Created and used for direct prompt/spec and image generation:

```text
slides/s10/shot-prompt-v1.md
slides/s10/shot-image-v1.png
slides/s10/shot-review-v1.md
```

No separate prompt review was required for this run because the user explicitly requested direct S-10 image generation and final image review only.
