# Style Reference (--sref)

## 매 한 줄
> **"매 Midjourney 의 reference-image style transfer flag"**. V6 (2024-01) 부터 도입 — 매 image URL 또는 sref code (numeric ID) 를 prompt 에 attach → 매 referenced image 의 visual style 을 generation 에 적용. 매 --cref (character) 와 더불어 controllable creative 의 핵심 tool.

## 매 핵심

### 매 syntax
```
/imagine prompt: <description> --sref <url-or-code> [--sw <0-1000>]
```
- **`--sref <URL>`**: 매 reference image URL.
- **`--sref <code>`**: 매 numeric "style code" (e.g., `1234567`) — Midjourney 의 internal style ID.
- **`--sref random`**: 매 random style code (V6.1+) — 매 creative exploration.
- **`--sw <0-1000>`**: style weight (default 100). higher = stronger style adherence.

### 매 multiple references
- `--sref url1 url2 url3` — 매 multiple style 의 blend.
- 매 weight per ref: `--sref url1::2 url2::1` (relative).

### 매 --sref vs --cref vs --iw
- **--sref**: 매 style only (color, texture, mood).
- **--cref**: 매 character / face identity preservation.
- **--iw <0-3>**: 매 image weight 의 prompt vs reference balance.

### 매 응용
1. Brand asset variation (매 일관된 visual style).
2. Mood board → final art (매 creative pipeline).
3. Style code library (매 reproducible aesthetic).
4. Series consistency (매 book illustration, comic).

## 💻 패턴

### Basic usage
```
/imagine prompt: a serene mountain lake at dawn --sref https://s.mj.run/abc123 --sw 100
```

### Style code (numeric)
```
/imagine prompt: cyberpunk samurai --sref 2589374610 --sw 200 --v 6
```

### Multiple references blended
```
/imagine prompt: a cozy library --sref https://img1.jpg https://img2.jpg --sw 150
```

### Random style exploration
```
/imagine prompt: portrait of a wizard --sref random --v 6.1
```

### sref code 추출 (after generation)
```
# Reply to a generated image with /describe — 매 sref code 를 capture
/describe <upload generated image>
# → outputs prompt + potential sref signature
```

### Weighted multi-ref
```
/imagine prompt: futuristic city --sref url1::3 url2::1 --sw 200
# url1 의 style 의 3x weight relative to url2
```

### Series consistency (book illustration)
```
# Page 1
/imagine prompt: a fox in a snowy forest, page 1 --sref 7891234560 --sw 150 --ar 3:4
# Page 2 (same sref)
/imagine prompt: the fox finds a glowing stone, page 2 --sref 7891234560 --sw 150 --ar 3:4
# Page 3
/imagine prompt: the fox returns home, page 3 --sref 7891234560 --sw 150 --ar 3:4
```

### --sref + --cref combo
```
/imagine prompt: knight in armor --cref https://character.jpg --cw 100 \
  --sref https://style.jpg --sw 150
# character identity preserved + style applied
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| 매 brand consistency | sref code (saved) + --sw 150-300 |
| 매 character series | --cref + --sref combo |
| 매 exploration | --sref random |
| 매 strong style enforcement | --sw 500-1000 (warning: prompt 이 약화) |
| 매 subtle hint | --sw 50-100 |

**기본값**: 매 --sw 100-200 + 매 saved sref code.

- 변형: [[Character-Reference-(--cref)]] · [[Image-Weight-(--iw)]]
- 응용: [[Style-Transfer]] · [[Brand-Asset-Generation]]
- Adjacent: [[IP-Adapter]] · [[ControlNet]] · [[FLUX-Pulid]]

## 🤖 LLM 활용
**언제**: 매 creative brief → Midjourney prompt 의 LLM 작성, 매 sref code library 의 tagging / search, 매 series consistency planning.
**언제 X**: 매 open-source self-hosted (use IP-Adapter / FLUX), 매 strict face identity (use --cref or PuLID), 매 photo retouching.

## ❌ 안티패턴
- **--sw 너무 높음 (>500)**: 매 prompt 이 무시됨 — 매 reference image 의 copy 에 가까워짐.
- **Multiple sref 너무 많이**: 매 5+ refs 는 muddy. 매 2-3 의 sweet spot.
- **sref + style emoji 충돌**: "--sref X cinematic dark" — 매 둘 다 style → conflict. 매 하나 선택.

## 🧪 검증 / 중복
- Verified (Midjourney official docs, V6 release notes 2024-01, V6.1 sref random 2024-07).
- 신뢰도 A.

| 날짜 | 변경 |

| 2026-05-08 | Phase 1 |
| 2026-05-10 | Manual cleanup — V6 syntax + --sw + multi-ref + cref combo |
