I typically like using Shadow Protection in View NX2, but sometimes see artifacts or halos that can be a problem. As a result, I'm using a lot of care in evaluating the right and wrong images for Shadow Protection.

Here is an example of what I mean. On this image I want to lighten the shadows. A quick adjustment in View NX2 looked fine, but when I got into Capture NX2 for a more detailed edit I saw some areas of the sky were incorrectly lightened. The uneven lightening of the sky is a significant problem and ultimately meant I had to remove all Shadow Protection.

Here is an example of where the problem areas are showing up. In this version I have exaggerated the settings to extreme levels to make the problem obvious. I set Shadow Protection at 100, Contrast at 100, and Brightness at -50. My normal settings would be much lighter - even with no Contrast or brightness adjustments and Shadow Protection at 10, I saw the halos.

This is not unique to Shadow Protection. Any image with fine detail has the potential for globally applied adjustments to spill over to adjoining areas. Even with selective adjustments, there is potential for a spillover effect, so you may need to remove the effect completely rather than allow the "feathering" built into the software. What this means is I may use minus selection or neutral control points to eliminate spillover in Capture, but you do not have that latitude in View where all adjustments are applied globally.
