GPT Image 2
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.

- 2Keep the composition cues such as framing, background depth and color palette, and adjust the style keywords to match your target aesthetic.
- 3Be explicit about what you don't want (no watermark, no text) and specify the output ratio if the model supports it.
