The workflow allows you to upload a portrait photo and use it as img2img reference to generate a 3x3 grid of 9 different portrait images you can use for training a character LoRA with FLUX or directly with a faceswap workflow.
The reference portrait must be a good quality hi-res image, but the workflow works also with old analogic photos (I tested it with a scanned old Polaroid from the '90s and the result was not too bad).
