Flux prompt anatomy cheatsheet (2026 working template)
Production-tested Flux prompt structure: subject → action → composition → light → style → quality. Plus negative prompt rules and what NOT to copy from Midjourney.
Six-slot prompt template
Flux follows literal description well — use natural language, not Midjourney flags. Put the most important visual cue first.
| Item | Description | Example |
|---|---|---|
1. Subject | The literal thing in the image. Use specific nouns. | A 35-year-old chef in a navy apron |
2. Action / pose | What the subject is doing. Use a present participle. | plating a dish under warm overhead light |
3. Composition | Camera distance, angle, framing. | medium close-up, eye level, rule of thirds |
4. Light | Source, direction, quality. Flux respects this precisely. | soft golden window light from camera right |
5. Style / lens | Photographic or illustrative style, lens choice. | shot on 50mm f/1.4, shallow depth of field, kodak portra 400 |
6. Quality + format | Quality cues at the end act like Midjourney's --stylize. | editorial photography, ultra detailed, 4k |
Negative prompt (what to exclude)
Flux negative prompts work — keep them short and specific.
| Item | Description | Example |
|---|---|---|
Bad anatomy fixers | extra fingers, fused fingers, deformed hands, mutated limbs | |
Quality killers | blurry, low quality, jpeg artifacts, watermark, text | |
Style killers | cgi, 3d render, plastic skin, oversharpened | |
Migrating from Midjourney
| Item | Description | Example |
|---|---|---|
Drop all -- flags | Convert --ar to natural language: '16:9 widescreen aspect ratio' as last sentence. | |
Convert --stylize to wording | High stylize → 'painterly, illustrative'. Low stylize → 'photoreal, documentary'. | |
Drop --niji | Use 'anime style, Studio Ghibli inspired' as part of the style slot. | |
Settings
| Item | Description | Example |
|---|---|---|
Guidance scale 3.5 | Default for Flux dev/Pro. Higher than 5 saturates badly. | |
Steps 28-40 | Past 40 the marginal quality gain is invisible. | |
Seed | Always pin the seed when iterating prompt phrasing. | |
FAQ
Does Flux understand camera and lens language?
Yes, surprisingly well. Specifying focal length (35mm, 50mm, 85mm), aperture, and film stock measurably changes output style.
What guidance scale should I use for Flux?
3.5 is the sweet spot for both dev and Pro Ultra. SDXL prompts at 7-9 will oversaturate when ported to Flux.
Can I use Midjourney prompts directly in Flux?
Not effectively. Strip -- flags, convert aspect ratio to natural language, and rewrite stylize parameters as adjectives. Re-tune seed + guidance.
