Use the greyscale preview
If you hold down Alt as you move the Luminance
Detail slider you see the image as a greyscale preview.
This hides the distracting colour information and enables you
to see any luminance noise more clearly. You can then smooth
it out more effectively. Click Done to finish.3
Reduce the luminance noise
Drag with the Hand tool to see a more detailed area
such as the face. If you set a high Luminance value it
will blur detail. You can restore some of the blurred detail by
dragging the Luminance Detail slider to the right. Set
Luminance to 12 and Luminance Detail to 65.AFTER
