Doesn't stop anyone from commenting. :)

Yes, sorry, I should have mentioned that.  At least, Adobe RGB is the
default colour space in PS, so I presume that if I load a Colormatch
RGB file without conversion, it is forced into Adobe RGB in a less
than predictable way.

Doubtless it makes sense.  One of the things I was wondering about was
why use Colormatch RGB at all rather than Adobe RGB?

OK.  This makes good sense and I can understand it.  So it probably
makes good sense to scan a master copy and leave it undersaturated,
and have a working copy which you tune to the desired result.

I'll try setting Colormatch RGB to be the default in PS and see if that
makes the reds behave any differently - I don't think it will.  The
combination of vuescan output from an LS30 using Colormatch RGB
just seems to do something strange to bright reds.

Thanks for the comments!
