I have a very good scanner profile that I use with the Epson scanner driver. I scan raw RGB, assign the scanner profile in Photoshop, then convert to a working space. the profile was made with the Hutch Color Target and Gretag Profilemaker Pro 4. this profile produces excellent results, but the Epson driver has very few options e.g. I cannot set enlarge/reduce, only resolution. this is why I am trying Silverfast.

I have the demo of Silverfast AI for Windows and I cannot get it to scan raw RGB. I have turned off color-managed transformations but I still end up with a washed-out image. the raw image captured with the Epson driver is dark and oversaturated but assigning my profile produces the desired result. I can't seem to turn off any color adjustments in Silverfast. when I do a pre-scan, the preview looks ok until it has finished, then something causes it to wash out.

I have tried to replicate the other workflow by using ICM for Scanner>Internal and Internal>Monitor, and have the Internal>Output set to RGB. In the Profiles the scanner is set to my Gretag profile, Internal is set to Adobe RGB (same as Photoshop's Working RGB space), output/printer isn't selectable, and rendering intent is Relative Colorimetric. However, this configuration does not produce the same results that I get with the Epson driver, even though I'm using the same profiles if not the same process.

I know this sounds like a bad workflow but that's what we need.

To scan raw with SilverFast you will need to set the gamma gradation to 1 (Option>General)

The workflow should be:

ICM for Scanner>Internal

Internal>Monitor = Automatic

Internal>Output set to RGB
In the Profiles the scanner is set to my Gretag profile, Internal is set to Adobe RGB (same as Photoshop's Working RGB space), output/printer isn't selectable, and rendering intent is Perceptual or Rel Col.
