Can you see my pictures (the ruined castle wall) now ? I can.
Yeah the clip with the lady looks nice at first glance - although you would not see artifacts like I found at that size. And I like that face but not on my screen for 1 year to become sharper...

I found out, that these magenta artefacts are exactly the same with my code, because it seems that we have the same unsharp mask approach. Moreover, they where much stronger, before I replaced blur(1.58) with binominal blur.

Somewhere I read, that unsharp masking produces color shifting. But if I use unsharp masks in my photo-raw-editor there is never any chroma shifting...

Anyway some tweaking with dehalo_alpha, mdegrain, gradfun and well balanced sharpening parameters gives excellent results in pretty short time.

Maybe someone out there`s got an idea ?
