## 💬 Prompts

### 🧠 BFS Face V1

```
face swap face from Image 1 to Image 2.
```

Alternative:

```
face swap face from Image 1 to Image 2. swap only the face and not the hair, the same skin tone from Image 2, same pose that Image 3
```

---

### 🧩 BFS Head V1

```
head swap from Image 1 to Image 2
```

Alternatives:

```
head swap from Image 1 to Image 2 with perfect skin match
Head swap from Image 1 to Image 2, keep all facial details and hair from Image 1, blend naturally with Image 2’s body.
head swap face from Image 1 to Image 2, keep all facial details and hair from Image 1, blend naturally with Image 2’s body, remove all hair of Image 2 and replace by hair from Image 1 and keep the same expression and head proportion as in image 2
```

---

### 🧬 BFS Head V2

```
head swap, transfer head from image 1 to image 2
```

---

### ⚡ BFS Head V3 (Recommended)

```
head_swap: start with Picture 1 as the base image, keeping its lighting, environment, and background. remove the head from Picture 1 completely and replace it with the head from Picture 2. ensure the head and body have correct anatomical proportions, and blend the skin tones, shadows, and lighting naturally so the final result appears as one coherent, realistic person.
```

## 🧾 Notes

* Works best with **Qwen Image Edit 2509** base model.
* For most versions, **Image 1 = face** and **Image 2 = body**.
  Only **Head V3** uses the opposite order (**Image 1 = body**, **Image 2 = face**).
* For improved alignment, you may use pose or face mesh control images (optional).
* Do **not** use or share results involving real people or public figures. I take no responsibility for any misuse of this model. Please use it responsibly and respect all likeness rights.
