With the above in mind, for those out there using NikonScan, does it
make any difference if you were to save as NEF vs TIF in 14bit (16bit)?
NikonScan will open and manipulate either one, so I'm not sure why
someone would save in NEF.

If there's no difference, and you then wanted to use the J2k instead,
how easy will it be to change these files in the future? If you were
considering further curves work, etc. would it be better to keep your
masters in TIFF?

once I've done an edit, I save as 8bpc lightly-compressed JPEG (PS
quality
setting 12).

When you say "edit" do you mean changes to that image, or selecting
amongst images? What size file does your 8bit file become?

Thanks.
