Denoise

Denoising is like cleaning up a messy picture to make it clearer and more detailed.

Start with Noise: Imagine you have a photo that’s covered in random dots or static (like an old TV screen). This “noise” makes the image hard to see.
The Denoising Process: Stable Diffusion works by gradually removing this noise step by step. Think of it as wiping away the static to reveal the hidden image underneath.
Guided by Your Input: You provide a text prompt (like “a sunny beach with palm trees”). The model uses this prompt to guide the denoising process, so the final image matches what you described.
Final Result: After enough steps, the noise is mostly gone, and you’re left with a clean, detailed image that matches your description.

In short, denoising is the process of turning a noisy, blurry image into a clear, sharp one, guided by your text input. It’s like magic erasing the mess to reveal the picture you wanted!

Using DPMPP_2M + Beta + 25 Steps + 1 CFG Scale (for Flux purposes)

RESULTS
Denoise from 0.85 to 0.9 generated best results.

SAMPLER + SCHEDULER

Using Denoise 1 + 25 Steps + 1 CFG Scale (for Flux purposes)

Discoveries:

KL_Optimal scheduler will provide only grey noise up to the very last of denoising. So, in order to get results, Denoise must be set to 1.0.
