## About

An extremely detailed, structured JSON prompt designed for image editing, focusing on achieving photographic realism while strictly preserving identity features (face, body proportions) from uploaded reference images, explicitly forbidding beautification or smoothing.

Prompt from YouMind OpenLab (github.com/YouMind-OpenLab). Prompt by Mukesh Mehraniya.
