Tune the
surfacing slider (the left one) to remove noise from surfaces without
losing details or bluring. The color images below show the surfacing
step results, while the gray images show what was removed from
originals in the calculation, for 3 values on 3 parts of the demo image.
Originals
Surfacing 20 : not enough, a lot of noise still appear
Surfacing 25 : correct, all noise remove, some details start to be removed, a few blur start to appear
Surfacing 40 : too much, details were lost, a lot of blur
Advanced tuning : you may try to tune the second slider (the right one) that, in some cases, can remove pixelisation effects on edges.
Advanced tuning : depending on the kind of noise you have, you can play with the "Chroma
modes", to avoid chroma artifact to be considered as images details. Be
careful, in this step, "Chroma modes" can produce more posterisations
(stair effects) on pure color continuous surfaces.
