  1. Many thanks, Jeff, for all your detailed advice. It is appreciated. Does anyone know how to get a copy of jpgicc.exe for Windows (Vista)? From what little I've seen about it, it might be useful. There are a couple of downloads on the net, but I'm not convinced they are safe.
  2. Thanks for that quick and helpful reply. I'm not trying to do anything high-powered — just scanning family photographs, and finding (unless it's my imagination!) that recent scans look "duller" than earlier scans when viewed on-screen. And blaming that on a gradual deterioration of my scanner. My only object is to view photos on-screen, or maybe print them, and have them look more like the originals. But I'm not seeking perfection, or consistency across different display devices, with all the complexities involved in that. I realize that, if the scanner is producing the same output from different inputs, this can't be remedied later. I was hoping that the "drift" of my scanner wasn't of that type, but would preserve relative differences, while not keeping the absolute values as they were in the original. But I don't know if that's a realistic assumption. I used a calibration target purchased from http://www.coloraid.de/ . I scanned it , but I haven't done anything with the profile generated from it, except to save the profile in a .icm file, while I try of discover how to make use of it. I hope this makes it clearer what I'm trying to do, and what I'm trying to avoid doing. "Just apply a profile" describes exactly what I want to do — apply the profile I generated to the photos I scanned, to compensate for scanner drift. I realize the photos may still look slightly different on different monitors and printers. Conceptually that seems simple, although it may not be simple behind the scenes, and I'd rather not get involved in a full CMS to do it. But it begins to look like I may give Gimp a go, though I first want to check out the links you gave to http://www.color.org/opensource.xalter One question: I've seen that some software, including Gimp and Photoshop, claims to be able to insert a profile in a jpg, but why do they not take a further step and produce a new jpg with the effect of the profile taken into account? Once again, many thanks.
  3. My aging flatbed scanner seemed to be losing its colour accuracy, so I got some profiling software (Lprof), and a calibration chart, and made a profile. My hope was to be able to apply this profile to recently scanned images, to improve their colouring. Does that make sense? I'm now looking for a way to apply the profile to my jpgs, to produce corrected jpgs. I don't really want anything as complicated as Photoshop or Gimp. Is there something that is straightforward to use for this seemingly straightforward task? Second-best would be a way to embed the profile in a jpg, so that an application like IrfanView could take account of the profile when loading the jpg, but again I can't see anything simple or free for this purpose. I would be grateful for any advice.
