It has been a problem for me since I started to use Neat Image how each slider in the Device Noise Profile affects the noise in the picture. Today when I tested the new 3.0 I got an idea.
Would it be possible - perhaps with a button under each slider. - And when you press one of these you highlight the areas in the picture that are affected by the corresponding slider.
Then it would be much easier to inrease noise reduction in the areas you want and decrease it where it is to high.
It would also be a good pedagogical tool when you try to explain the sliders.
With Best Regards
