Slightly off topic, hopefully mods won't mid.
Can anyone recomed monitor calibration hw/sw that works under linux? _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

I used a cheap huey (see: http://www.pantone.com/pages/products/product.aspx?pid=79), together with argyllcms (see: http://www.argyllcms.com/) to do a good calibration of my monitor. The huey works fine out of the box with argyllcms. Before the huey was sold by Gretag-Machbet, later was sold by Pantone, now seems sold by X-Rite, but it's exactly the same hardware. Also, there should be a cheaper "basic" and a less cheaper "pro" version, they have the same hardware, the only difference is the software (for Windows and Mac Os X) they give you; since I was on gnu/linux, I got the "basic" version The topic is not so easy, but following the argyllcms documentation and some posts from this blog http://jcornuz.wordpress.com/ I found my way out, and put some notes in my blog, so I won't forget. If you understand Italian, they're here: http://gerlos.altervista.org/pinguino-fotografo/gestione-colori-gnulinux Later on, I discovered dispcalGUI (see: http://hoech.net/dispcalGUI/), just a GUI frontend to argyllcms, and now I use it when I need to calibrate a monitor, it's very comfortable. I remembered that for a while I tinkered with a littleCMS-based GUI for monitor calibration, but found it quite awkward to use, and there was a lot thing I didn't understand, so I suggest you to avoid it.

What I do instead is that I create hardware calibration profiles in MS Windows using the tools from the vendor (these profiles are stored in the LCD and can be switched using hw buttons). I personally use the predefined sRGB, AdobeRGB and then full monitor's gamut with D50 white point. As a second step, I profile the display using argyllcms tools as usual - that is, I skip the calibration process (use native values). This affects only the VCGT in the graphics card, but honestly, the changes are minor. Due to missing linux support, I have to manually load the proper display profile depending on which hw profile is "active".

Does anybody know, or think, that by using this I could avoid the need for calibration and colour management, provided I always work in SRGB colour space?

Does anybody know, or think, that by using this I could avoid the need for calibration and colour management, provided I always work in SRGB colour space? Afaik, no, you couldn't avoid calibration, since the video card needs to know something about how to map colors on the screeen, and I'm not sure that it does the "right things" out of the box. At least, I'd do a check with a colorimeter to be sure that everything is right. But if you are happy eyeballing a gamma chart on the screen, it could be ok anyway... regards gerlos -- "Life is pretty simple: You do some stuff. Most fails. Some works. You do more of what works.

This means everything should be in the ball park right out of the box. Nerd > /dev/null 2>&1 Here's what I do: Take a picture with your digicam, preferably one using the whole histogram with lots of different colours, skin tones and such. Send it off to have it printed in a largish format specifying "no adjustments whatsoever"! Then get the resulting print and check to see where the monitor picture and the print differ. Adjust the knobs and dials on your monitor until your built in stereo optical colorimeter tells you they are as close as they'll ever get. Presto, you now have an end to end color calibrated system set up. It may be less easy to tweak, requiring actual foot work to do, but it works if your printer (or printing service) can deliver consistent results. I've done 12 large pictures for an exhibition this way and never had a single complaint about the colour being off.

This is a bit misleading information. Short answer is that if Mark believes that his monitor is capable of sRGB gamut and displays colours as they are characterised by sRGB ICC profile, he can use sRGB profile as the monitor profile in various applications. However, I would doubt that the monitor is of so high quality and he would probably get more reliable colours by setting the sRGB settings in the monitor (quasi calibrating it) and create a custom profile with Huey, Eye One etc. (characterise it). The ICC profile can do a bit of calibration, too - it is done via VCGT tag, which adjusts the video card settings. To use the VCGT, one needs a VCGT loader - like dispwin tool from argyllcms.
