I've been watching this and will try what has been suggested to line the jpeg with the NEF.
I have Photo Ninja which is perfectly okay for broad changes to NEF files and I am happy with that.
However, one of the beauties of CNX2 is the ability to very quickly change or adjust the colour of somebody's tee shirt, judogi or anything else with the U-points on the NEF. That cannot be done with any other raw editor and using the the U-points of the NIK collection on a jpeg does not work unless it is very small adjustments.
That is why I am still working with CNX2.
