NC is Nikon Capture. Don't know what version comes with your camera. Must be a trial version. You can google a register code by yourself. What I have was version 3.5, then I upgraded to 4.1. 4.2 is just out, I am going to try it out this week.
Home work for you:
1. find NC, adjust white balance.
2. PS your photos afterwards.
3. Add frame and signature
4. Upload to this post again.
