SilverFast Ai Studio offers two additional slider controls with the AACO expert dialog. If you notice a loss of saturation in the shadow areas, use the Saturation slider to achieve more vibrant colors in the dark areas. The Radius Level slider defines the size of the shadow region to which the AACO effect applies.
