Thanks Thomas. I tried using Capture NX-D. It seem to have limited functionality. Perhaps, I should review documentation on CNX-D to get a better understanding of how the app works.
One of the few things that I enjoyed about Adobe Camera Raw was it's ability to open NEF files and making some adjustments, when necessary. All it did was produced a small XML file that contained the adjustments. I always save the results as a PSD file, and work from that. At this point, I will try DNG and Capture NX-D.
I have Adobe CC at work, and I just installed the latest Camera Raw that supports the D5's RAW format. I did a minor comparison of what DNG produced versus what Camera Raw produced. Visually, they both appeared the same. Again, it was a minor comparison. I will compare the EXIF data when I am not crazy busy at work and do some print comparisons as well.
In the end, if I am forced to subscribe to the monthly Adobe CC subscription, it better do a great deal more than simply open the D5's NEF file, compared to the features of CS6.
Thanks again.
