Use when writing or diagnosing portrait lighting and image texture prompts from references, including soft backlight, direct flash, oily faces, distracting backgrounds, skirt coverage in seated poses, or migration to local models such as Z-Image.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# 人像光线配方

> **这是一套判断流程，不是词表。** 每一步只做一个决定，每个决定都有判据；
> 判不出来就停在那一步，别往下走，也别改措辞去撞。
>
> 证据来自 z-image（本地 ComfyUI）上 ~280 张**同种子单变量**对照
> （其中 76 张是 2026-08-30 补的成像系统那一轴），加六轮成品迭代
> （约 300 张候选，人工挑片，六轮里有四轮是整组推倒）。
> ⭐ **2026-09-22 追加第五轮实践**（情绪 / 眼神 / 光影 / 冷暖 / 多人这条线，四批约 90 张候选）：
> 新增 §4.1 那三条（动作 / 姿态 / 字数）、第 7 步的冷暖那一节、§2 ④ 的穿搭落地版、
> §6.3 的皮肤正向化，以及诊断表七行、附录 D ⑦条。
> 逐轮数据在 `docs/对照实验.md`，**30 张成品和它们各自的完整提示词在 `docs/配方全文.md`**
> （配图在 `assets/`，编号一一对应）。
> ⭐ **要直接抄就抄 12~30 那 19 条**，它们是按本文件重出并人工挑过的。
> ⚠️ 01~11 写在 2026-08-29 归因之前，其中七条仍带着「和她的脸一样高」和
> 「眼睛里有一颗清楚的反光点」两个已知 bug（第 3 步② / §8①）——
> 文档里没改它们的正文（那些字就是配图的来源），但逐条标了复用时要改成什么。
> 提示词是**纯中文整段**，粘到豆包 / 即梦 / 通义同样成立，不用拆词、不用配负向。

How to install

The exact contents, by fingerprint

mdr add l-trunks/ai-portrait-light/portrait-light@sha256:27ef134476793ee8

The line at the top of this page pins the label git:20261029.4def521, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
