Thanks for the script LaTo. I may have to try it out some time
Still, When I fed Smoothadjust with a non mod4 source and smoothing strenght maxed out the erronious result that came up looked a lot like box blur to me. Maybe it's naive to assume that's what smoothadjust uses but I'm still not getting satisfactory results on the image I mentioned before with the newest version.
No chance of seeing a median Smode 5?
