How to Get Great Results
- Step 1
Keep prompts concise
Use 1–2 sentences that define subject, style, and lighting. Save detailed material lists for a second‑phase model.
- Step 2
Iterate fast, then upscale fidelity
Lock composition and mood with Schnell, then move to Flux.Pro/Juggernaut for high‑detail final images.
- Step 3
Use img2img for restyle
When you get a composition you like, send it through img2img to nudge palette, lighting, or texture while preserving layout.
- Step 4
Avoid overloading
Long adjective chains can create mushy detail at low steps. Prioritize camera, light, and a few key attributes.
