Concept

1. Increase CFG to enhance image intensity and details.

2. CFG will cause the image burned, so DynamicThresholdingFull and AdaptiveGuider are required .

3. Separate Sigmas for denoise sampling: Apply CFG in the early stage,(high sigmas) then reduce it back to CFG 1.0 in the later stage(low sigmas), as CFG 2 and above doubles the sampling time.

4. Inject noise between sigmas to improve image details.

The testing model is Q8 version of：

GGUF: FastFlux Unchained (FluxUnchained merged in Flux.S)

but you can use the workflow on dev or other models
