Flux is the generator people open when a portrait has to survive a close crop. The prompts below are studio setups: light, lens, and surface detail. Paste one, then change the wardrobe or the background. Leave a real person's name out of the prompt unless you have the right to depict them.

How to use them#

Start with one sentence from the list. Add only the detail you care about next: hair, clothing, or background. If the skin looks waxy, repeat natural skin texture and visible pores. If the face looks like a specific public figure you did not name, regenerate. A likeness you did not ask for is still not a photo of that person.
