GPT Image 2 JSON color grading UGC model sample

### Full prompt
```text
Analyze this photo and give me a detailed JSON prompt that recreates it. Break down the color grading and every exact color in the photo. Then use that JSON as a reference to generate a person holding the product. Save the generated photo as a character reference and attach it to every future generation for facial consistency. The JSON controls the lighting and color grading while the model handles the character.
```
