I looked at these but was highly unimpressed. When you use profiles you need
to scan consistently - i.e. trun off all autoexposure settings in the scanner
or anything else than can be variable across scans. Knowing which settings
were where with these supplied profiles is impossible to tell. It is best to
start again from scratch.

Nikon doesn't have proper ICC colour management in its scanning software so
any profile you make will have to be applied afterwards in Photoshop or
another ICC compliant program.

I don't think Vuescan has built in profiles for each scanner. That would be
very difficult to do without a reference chart. Yes it has film profiles which
helps manage colour with negative colour film but that is something else
entirely.

Yes much, much better!
