this photo and give me a detailed JSON prompt that recreates it. break down the color grading and every exact color in the photo
(use Opus, not Sonnet. Opus has stronger visual analysis and writes more detailed JSON)
paste that JSON into ChatGPT
upload your product image and prompt:
using this JSON as reference, generate a person holding my product
save that generated photo as your character reference
attach it to every future generation for facial consistency
you now have a consistent UGC model that works across any product
the JSON controls the lighting and color grading. GPT image-2 handles the character. you control the product placement.
the #1 tell on AI photos is flat colors and a grainy look. this method removes both.
5 minutes to set up. unlimited variations after.
