FLUX.1 Fill pro Portrait Style Rewriting: Realistic and Artistic Dual Samples

Demonstrating the local repainting capability of FLUX.1 Fill [pro] by editing the same portrait under two style prompts: one follows a realistic route (preserving skin texture and natural light), and the other follows an artistic route (painterly brushstrokes and color blocks). The setup requires an original image and a binary mask of the same dimensions as the original image; white areas are repainted according to the prompt, while black areas remain unchanged. This work uses an all-white mask to perform an overall style rewrite of the entire portrait, thereby isolating and exposing the "prompt differences." It is suitable for developers, before integrating FLUX.1 Fill pro, to observe how mask range, guidance, and prompt_upsampling affect the output style for the same base image. It can also serve as a prompt reference for local retouching, skin replacement, and background replacement of portrait assets. Note that this model is an editing model, not a text-to-image model; results depend on mask quality and prompt description, and fine structures may still require multiple attempts.
