Re: filmscanners: Profiling scanners...

Vuescan utilises an internal matrix which does the job of a scanner 
profile. This calibration is derived by Ed from a Q60. Ed has 
integrated this into VS (rather than implementing it as a proper, 
changeable profile) to stop people stealing it and using it in other 
software. However it does limit you to a generic profile for the 
rather than one you make yourself.

I can see Ed's point of view, since scanners generally seem to diverge 
little from a generic spec so his characterisations are fine. However 
might do better to change the architecture to use proper profiles, and 
us his profiling tools - Vueprofile? - as well :)

As a workaround, if you have a DIY scanner profile and Photoshop, you 
obtain completely raw high-bit scans from your scanner via Vuescan and 
apply the profile in PS.
