By activating the ACR checkbox in the Selective Colour
Correction dialog SilverFast ACR will immediately analyse the
image and apply a correction. Typically this will result in a degree of saturation
increase/decrease that is greater than required. The above image shows what can
happen when ACR is left to its own devices. However, moving the ACR
slider slightly to the left will reduce saturation to a more acceptable
level. Using the ACR slider I reduced saturation slightly and obtained the
image shown below. With a little more effort I could easily reduce saturation
further without sacrificing the overall effect.
