Stable Diffusion

So I recently switched to ForgeUI and they have plenty of features integrated out of the box.

In the context of FreeU, what exactly B and S are modifying? I spent a whole day trying to wrap my head around their exact functionality. Some say keep B>1 and S<1. Some say it adds sharpness and saturation, and the preset on their github didn't work for me, well atleast with the prompt I was tweaking.

But while I was fiddling around with FreeU, I observed lot of drastic modification in the generated image, which gave me hope that it just might be tool to realign the image in accordance to my prompt.
