mikael1 Posted November 29, 2004 Share Posted November 29, 2004 I'm pretty sure I'm on the right track here, but I just want to makesure I'm doing the right thing as I wont have the chance to drumscanthem again. I've scanned dozens of old negs on a ScanMate 5000 into 16bit RGB files. The scanner has no device profile and the softwarecould not assign workspace profiles in 16-bit (weird limitation). Now I'm about to open the untagged raw scans in Photoshop and as therewere no profiles attached during scanning I should be _assigning_ aworkspace I've settled on when Photoshop asks, shouldn't I? After assigning I will do inversion and and color correction and thensave the file. Sounds reasonable? Thanks in advance... Link to comment Share on other sites More sharing options...
andrew_rodney1 Posted November 29, 2004 Share Posted November 29, 2004 Yes but the question is, assign which profile? You might need to assign the display profile to produce a matching color appearance to a scanner that doesn't understand profiles. But that's really not ideal. BTW, you should be able to create and use an input profile with Color Quartet. Link to comment Share on other sites More sharing options...
danny_liao Posted November 29, 2004 Share Posted November 29, 2004 The most popular profile to assign is Adobe RGB 1998. That is what you should work with in Photoshop. Link to comment Share on other sites More sharing options...
jespdj Posted November 30, 2004 Share Posted November 30, 2004 The scanned images are in the native colour space of the scanner. You should have an ICC profile that describes the native colour space of the scanner. Assign that to the untagged image, then convert to a standard colour space such as Adobe RGB. Ofcourse, you have a problem because you don't have the colour space of the scanner..... Directly assigning Adobe RGB to the scanned image only makes sense if the scanner's native colour space is close to Adobe RGB - if not, the colours will probably shift noticeably.

mikael1 Posted November 30, 2004 Author Share Posted November 30, 2004 Thank you all for the answers... This actually leads me to something else :) Yup, the ColorQuartet software allows an input profile, but I'm not sure my teacher likes me fiddling around with his stuff (I'm at a school). Colorshifts isn't a problem, these are B&W negatives & the only "color correction" to be done is desaturating the image. Will assigning the ProPhoto RGB workspace still be a problem? I figured I'd go for RGB for the scanning of B&W negs as I've seen no recommendation of a grayscale profile (although dotgain 20% seems common) like Adobe RGB or ProPhoto RGB for RGB. Seems like in a grayscale workflow the work space is determined by what you output the data to (dotgain) while working in in RGB the workspace is independent of the output (Prophoto RGB or Adobe RGB etc). So, settling on a grayscale profile will also optimize the file for one specific output? Also, as the images most likely are gonna go through some sort of toning (through HSB or curves) they will have to be converted into a RGB space later, which would be a lossy process, right? The only backside would be the much larger size of the files. But hey, I can live with it. Any ideas? Link to comment Share on other sites More sharing options...
andrew_rodney1 Posted November 30, 2004 Share Posted November 30, 2004 -->Will assigning the ProPhoto RGB workspace still be a problem? Yes! Assigning ANY profile that doesn't describe the meaning of the numbers is not good. Either get your teacher to understand the role of input profiles or try assingning the display profile which will at the very least get close to producing the same color appearance in Photoshop as QC. Or you can just Assign all the profiles you can find until you hit upon one that produces acceptable color appearance but what a kludge. Link to comment Share on other sites More sharing options...
