iif(FS>(ABL/65535), FS*(1-FS)+SS*FS, FS)
What this this do is add the sharper data in on brighter areas (which intrinsically have better SNR) without affecting the dimmer areas and won’t affect the background at all.
Typing this on my phone at work but I think that code will work in PixelMath.

That's a great idea Colin.Will give it a go. Thanks
