Those of us who are long term users of PhotoLab have known for years that Clearview Plus should rarely be used other than for the occasional removal of atmospheric haze. That is the purpose for which it was designed, thus the name of this tool. For any other purpose, it should only be used at very low settings, if at all.
For those of us with a license for FilmPack we tend to use the six Fine contrast sliders instead. The Micro Contrast slider should also be used in moderation. High settings can add unpleasant harshness. In many situations the Fine contrast sliders provide more nuanced adjustments.
