Hi, after posting on ICC profiles, I realized (via several online documents) that the first step is actually, to calibrate the monitor. I found two tutorials on this, but when trying to calibrate my Fujitsu-Siemens monitor (Scaleoview 19-2 TFT) by using the first tutorial at scarse.org, I had to realize that this didn't work at all. After checking the system gamma and correcting it according to the patterns at the site
see http://www.scarse.org/adjust/ I wasn't able to set either black (http://www.scarse.org/adjust/black.html) or white (http://www.scarse.org/adjust/white.html) point. They are simply out of the range of what I can adjust via the OSD (On-Screen Display). Now I am asking myself if this tutorial is probably only for CRTs. I then tried another tutorial by Norman Koren at http://www.normankoren.com/makingfineprints1A.html This seems to be much better, and he mentions a variety of other online sources with test images, software for calibration/ gamma correction, etc. But when trying to correct the gamma of my system, I got two different correction values (monitor: see above; OS: Ubuntu 8.10/i386): 1.4 (http://www.scarse.org/adjust/gamma.html) 1.4 (http://www.normankoren.com/makingfineprints1A.html#gammachart) 1.76 (LProf -> http://lprof.sourceforge.net/) My question: What is the proper correction value? 1.4? Does anyone know what the differences between calibrating CRTs and TFTs are? Those issues aside, I find the topic very exciting. For those interested, here are a few recommendable sites I came across: - http://www.scarse.org/adjust/ (see above) - http://www.normankoren.com/makingfineprints1A.html (see above) - http://www.digitaldog.net/tips/index.shtml (reference images & more) - http://www.eci.org/doku.php?id=en:start (ICC profiles for offset printing, docs on the proper use of PDF, etc. - http://lprof.sourceforge.net/ (calibration software for Linux) - http://docs.scribus.net/index.php?lang=en&page=moncal (LProf HOWTO at the Scribus site) Cheers, Claus -- Claus Cyrny : Webdesign | Grafik | Fotografie :: Web: http://home.arcor.de/ccyrny/ ::. :: Fotos: http://photo.net/photodb/slideshow?folder_id=714471 ::. _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
