Portrait Consistency Set (Same Person, Three Expressions) Prompt for FLUX

This is the FLUX version of the portrait consistency set (same person, three expressions) prompt: one person, three expressions, one unchanging face — the casting-sheet set used to anchor a character or a real person's likeness. It is formatted the way FLUX takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.

Reference image — keyframe

Attach a reference image: choose a file, drag & drop it here, or click here and paste. It never leaves your browser.

Attach reference image

Push copies this prompt with a reference line naming your image, and downloads the image file — attach it in the model to complete the pair. This page stages the pair for you; it cannot upload into the model itself (sites cannot reach into each other), so the final attach happens there. The image is downscaled to at most 1024px and stored only in this browser, paired with this prompt. If browser storage is full, it is kept for this visit only.

The deliverable — and how to check it

Deliverable: one triptych image with exactly 3 headshots — neutral, smiling, serious — of the same person, same hairstyle, wardrobe, backdrop and light in all three. Acceptance check: swap test — cover two panels; the visible face must be unmistakably the same person as the other two when uncovered. Any change in face shape, hair or age fails the set.

Using this prompt with FLUX

FLUX reads natural-language scene descriptions with photographic vocabulary - subject, lens, light, texture - better than tag soup. This version is written as a rich descriptive sentence with the technical details a photographer would specify.

What this route costs — and how to pay less

Cost structure: metered per image through Black Forest Labs' API and partner hosts; some FLUX variants are open weights that also run locally at no per-image cost. Hosted playground access is credit-based. The same prompt is pre-configured in this library for every major model, so you can run it on whichever route fits your budget — comparing the structures before you generate is a free way to save money.

Replace the bracketed placeholders — [PERSON DESCRIPTION], [WARDROBE], [BACKDROP COLOR] — with your own details before pasting.
