After I upgraded my computer from Vista to Windows 7 all of the pictures except very small thumnails had a sreong green tint that could not be corrected.
After much frustration I discovered that the color management profile for my monitior was being used instead of NKsRGB.
To fix the problem go to Edit in ViewNX then Options then Color Management. In the first section default RGB color space browse for the color space you prefer and then hit OK.
The reason I use ViewNX is to determine which pictures to keep. I like the ability to make the pictues almost full screen size and then cliking thru them like a slide show.I would prefer to do this in CaptureNX2--is there a way to do this
