PLEASE HELP!!!!!
HI, I'm trying to get a print out (onto paper) that matches, in color an original photo that i scanned . Would it make sense to scan the original photo (with a photo scanner) and scan an attempted print out of the right color side by side, open them on gimp, find the difference in hue, saturation, rgb etc., and then use this difference between the two scanned images (say the difference between the two scanned images, again, the phtot and the attempted correct print out, is plus 7 green) to correct the original image ON GIMP (which I printed out and it became the attempted correct version) by adding plus 7 green, so that when it's printed out..... it will be the same color as the photo I scanned? In other words, I know that scanning something then printing it out will not yield the exact same color as the original....... but can i use a scanner for comparison of color (i.e., the scanner will distort two images equally, right?). thanks, tess. -- tess anne (via www.gimpusers.com) _______________________________________________ Gimp-user mailing list Gimp-user@... https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user |

Gimp can probably to a better job of doing the corrections if one can grasp the fundamentals of gamma correction too. Or at least that seems to be the major time waster for me, since correct use of the gamma in the weakest color can compensate for some, but not all, age fading. I have not done a 'due diligence' search of the wiki (the do it your own self old (75) fart male syndrome at work) to see if there is a good starter tutorial on that subject. There might be, if not, one needs written as its one of those things that can make you look like a magician to kin with older pix. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Googling on "color management" and reading the first few hits would be a good start. Next could be to buy a book on the subject. / Martin -- My GIMP Blog: http://www.chromecode.com/ _______________________________________________ Gimp-user mailing list Gimp-user@... https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user |
