Flux 1.1 Ultra
“Ultra” is not marketing fluff: use it when the frame goes to portfolio, billboard, or tight layout. You get fewer compromises on anatomy and materials than on fast samplers.
When Ultra is not overkill
- Hero campaigns, large formats, print and OOH.
- Hard light, reflections, “heavy” materials — glass, water, metal.
- Frames people will zoom on a retina display.
