New try with a new Spyder 3, but still not satisfied. dispcalGUI run this:dispcal -v -d1 -c1 -yl -P0.474187380497,0.455830388693,1.0 -qh -t6500.0 -b140.0 -gs -f0.0 -a13.8 -k0.0 -A4.0 -B0.5 colprof -v -qh -aX
I got a perfect greyscale. From black to withe with all tones. But the calibration gave a red cast to some tones on the screen. The color #BEBEBE for instance. I got that color in my filemanager and then I take a screenshot it showed up perfect, as I can se it, in Gimp. Then I look at the vitpunkt.tif and svartpunkt.tif (Swedish for whitepoint and blackpoint - it shows neutral tones from tone 255 to 244 and tone 0 to 22 - download here http://www.profiler.nu/filer/Skarm.zip ) I see red casts in some of the tones. This occur both in color managed Gimp and in not color managed applications.
And then I locket at pictures in Gimp and Geeqie they looked the same but in Firefox then look like in not color managed applications. I must say that in Gimp and Geeqie most of the color has disappeared, the colors looks out washed. My pictures have never looked so dull. But I suppose that it can be alright, and that it is something wrong with Firefox. I read the little discussion here about different profiles. I chosed to do a 'XYZ LUT + MATRIX' profile.
Color management will soon drive me nuts. There are questions like can I trust the Spyder 3 and have I set up color management right in Gimp and Geegie. In Gimp I have done like this:
* Mode of operation:* Color managed display *RGB profile:* None *CMYK profile:* None *Monitor profile:* None /Try to use the system monitor profile/ = *Yes* *Display rendering intent:* Perceptual *Print simulation profile:* None *Softproof redering intent:* Perceptual /Mark out of gamut colors/ (grey) = *No* *File Open behaviour:* Ask what to doIs that alright? And that about the Spyder 3, does it seems that it help me, or should I send it back and wait until I can afford a spectrometer, after that I first have payed my fancy but possibly wrong calibrated and therefore useless monitor? ;-)
Now I will go to bed and cry myself to sleep... Magnus
