Re: filmscanners: Device Profile in "VueScan"

I am not sure this has changed but I think so - perhaps Ed will answer this.
It may have changed when he (not too long ago) added the "Device Profile"
option to the color space menu for this very reason.  I believe it picks up
the scanner's color profile selection because I had set my Nikon LS-30 for
ColorMatch and Vuescan for "Device Profile" and scanned a negative, and in
some fashion I saw that the image was profiled in ColorMatch (I don't have
PhotoShop so I'm somewhat at a loss to check for sure).

|     Vuescan is not aware of any association any scanner has with any
| device profile located anywhere on your computer.  When you choose
| "device RGB" it is up to you to find (or create) that profile and
| associate it with the scanned RGB values.
|     Otherwise, if you choose one of the other color spaces, Vuescan
| will convert from the device profile (as determined by Ed Hamrick and
| built into Vuescan) to that color space.  If you choose "device RGB",
| you need to be careful of whether the media chosen is negative,
| positive or image, before you will be able to appropriately associate
| ("assign") some device profile you may have.  I believe "image" and
| "slide film" is straight-forward (assuming you have a manufacturer's
| device profile), ... "negative" film is not straight-forward because
| the RGB values are handled by Vuescan's own profile for the scanner.
|     (my understanding goes back to experience and correspondence with
| early versions of VS v.7 ... has anything changed?)
