I'm pretty sure to get in trouble for saying this, which is not a "new sensation" for me. ;-) If you're archiving, "Device RGB" would *not* be the color space to choose, because it reflects a device that may be broken and unserviceable or out of production in 1-10 years. By the same token, I would not use any of the current "choices" of color space, because they may also change or be discontinued in a matter of time. "Backward Mobility" in electonics and software might be a nice thought, but it's more observed in its absence than its adherence! I feel that sRGB, as limited as it's said to be, will be around a bit longer than many of the other standards, since there's been a lot of television commited to that particular standard (if "standard" is still a working word :-) ). I'm not Nostradamus, so my predictions are no more reliable than any other guy's--but I'd say that JPEG and sRGB will at least be *accesssible* for a while to come. TIFF, Gif and some other formats will be, too. Beyond that, cross your fingers and save your negatives! :-) I'm hoping that other--wiser!--heads will pop in here, and soon. It's not a small problem.

I believe if you would have had Photoshop, you would have found no profile had been associated with the scanned image with "device RGB" chosen. (How did you determine "I saw that the image was profiled in ColorMatch"?) The RGB values are intended to belong to the device, but no profile is embedded (note the color space option does NOT refer to any profile ... the option is "device RGB"). I believe Ed added this option so that, with Photoshop, you could then "assign" the appropriate profile ... for example a device profile which may have shipped with your Nikon. You could then properly "convert" to a working space of your choice. However, I have found this doesn't work with negatives, because when subtracting the mask Vuescan unavoidably touches the RGB values with Ed's built-in device profile for the scanner ... therefore you can no longer use the Nikon device profile because it is different than the one Ed built-in. You CAN use the Nikon device profile if you scanned a slide because Ed's profile doesn't come into play. You almost have to have Photoshop to properly play with and evaluate this "device RGB" option. If you are using a different "non-profile savvy" image editor, you are probably better off choosing sRGB in Vuescan. shAf :o)
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).

Re: filmscanners: Device Profile in "VueScan"
I think you well find the following: There are two Minolta profiles on your system (c:\windows\color if using a PC).One for negative and one for positive images. The Vuescan help file states that "Device RGB" is only useful if you select "image" as the media type. >From the Vuescan help file"...The "Device RGB" color space doesn't embed any ICC profile into the TIFF or JPEG files, and outputs images in the color space of the device. The "Device RGB" option is only useful when "Device|Media type" is set to "Image" Note that no profile is embedded. The Minolta profiles are not recommended as "working spaces". I am not sure what you are trying to do, but suspect you would be best served to use Adobe RGB as you working space, select either image, slide, or negative, as appropriate, under "Device/Media type", and have Vuescan tag the crop files as Adobe RGB in the color tab. Vuescan well use the appropriate Minolta profile to characterize the scanner in producing the scan, and the tagged file will then open in Photoshop 6 without need for further conversion.

To the best of my knowledge Device Profile applies to Scan and to RAW scan. As to your second question, yes - "Device Profile" transfers the profile of the scanner.

filmscanners: Device Profile in "VueScan"
Hi I use Minolta Dimage Dual II with Vuescan. In VueScan, Is it good to use RAW scan or Scan with DeviceProfile? In VueScan, If I select "Device Profile", is it the profile of the scanner? In my PS6.0, I see two profiles related to "Minolta Dimage Dual II ", but none on Vuescan. Thanks in advance Ramesh
