Hmm, no, I have the Colorvision Spyder. I was rather assuming that if the profiling was done on my monitor, being driven by my video card, that it wouldn't care what was driving it (windoze or Linux) That might be a problem though if that's not the case.

Aha, yes, that'll be a good starting point. Thanks. I noticed that I don't seem to get very good input via ufraw by default. Using the profile for a Nikon D70 (same sensor, so they say) seems to produce much better results, but I wasn't sure if that was dumb luck. I'll look into getting this setup first. > I currently recommend CinePaint as your image editor. It has full CM > support > and handles high bit depth images. Also very valuable, thanks. I was hoping GIMP would do the job, but it seems to be rather behind the curve wrt color manaement.

Actually, the process is this: Go to mediastreet, buy ink (and perhaps paper) from them, download a (two page) target image, print the image, mail it to them, then they profile it (apparently on some expensive hardware, such as you describe) then they return--and publish for general use by other customers. So, yes, this was created on my very own hardware with my favorite paper, so one hopes it's pretty accurate. > There is a learning curve to all of this stuff so be prepared to > struggle with > all of this at least a little and some of it alot.

At least I've some clue which roads to try to go along, and in which order. Thanks, Simon __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
