This question will reveal my utterly amateur level using post processing software. I only recently (6 months?) upgraded from D70S to D7000. I was still using PictureProject with my D70. Now I am using ViewNX 2 v2.5.1.
Can I return back to the original NEF file after editing the image in ViewNX 2 and saving my edits? If memory serves, I could do this in PictureProject.I have not figured out how I can do this in ViewNX. As a result I have been very cautious in my editing so far.
