Dear Tim,

Let's say I have a Leaf 45 and I'm scanning 16 bit raw scans. How would I

Your first question is : can your profiling application accept 48 bit RGB
images? Or will it only work with 24 bit images? That kind of limit what you
can work with.

I would Assign your scanner profile on open in Photoshop and convert to
AdobeRGB for further editing. Although, I have found that Joe Holmes's
EktaSpace does not clip any of the original XYZ data as opposed to AdobeRGB
which slightly clips in the green. Whatever profile you select as your "RGB
Working Space" in Photoshop, you definitely need to tag the image with it
upon saving.
Now, why do you talk about the "RIP": can you do these ICC conversions in
your RIP? Make sure they would take place absolutely the same way you would
carry them in Photoshop otherwise you will lose control of the color.

Yes, Silverfast allows you to set the conversions in scanner software
itself. So, you would be able to "see" or softproof colors right into
SilverFast the same way you would in Photoshop by scanning raw and then
Assigning on input. AGFA Foto-Look also does that and so, I find, the
majority of ColorSync-aware scanner driver software these days.
Now, I have not studied SilverFast enough yet to tell you exactly how
SilverFast internal workings is able to mimic your Photoshop workflow.
Anyone willing to share?
