dispwin profile.icc only loads calibration, dispwin -I profile.icc
additionally installs the profile (copies to appropriate location in
the filesystem) and sets it as default for the display.
After installation, to reload the calibration you can use dispwin -L
which loads the calibration of whatever the current display profile is
(dispwin -c -L might be more robust because it clears the current
calibration before loading).
I think that you have to restart firefox to get changes in the
profile to be recognized. I have the color management extension
installed in firefox and there is a box where I can specify the
profile filename; when I specified the color swapped profile and then
restarted firefox I did observe the swapped colors used in firefox.
Yes, I restarted Firefox, but still no go. If I specify the profile it
should use with the extension, it works.
So it only uses a profile if you specifically give it the filename. I
wonder if firefox has a different idea than dispwin about where the
profile resides.
Wouldn't it be optimal in this case to instead calibrate the display
to sRGB so that I only have one layer of mapping (in 8 bits) to
display the data there? In other words, I should get less banding
and artifacts when viewing the sRGB source data if I calibrate the
display to sRGB even though this is farther from the display's native
response. It seems like I should calibrate to the expected color
space of my data.
If it is foreseeable that most if not all images you view are actually
sRGB (and we assume that sRGB images indeed should be viewed with a
sRGB gamma, and not just encoded with it but viewed on say a gamma 2.x
monitor), then I agree it is surely a good idea to use that as tone
curve when calibrating.
Here you seem to be raising the point that I was really asking about,
which is: how should sRGB tagged images be viewed. The images from my
camera, which I presume are sRGB tagged, looked a bit washed out when I
viewed them with a sRGB calibration as compared to the gamma=2.4
calibration. But if sRGB images are supposed to be viewed on a
gamma=2.4 display and I have color management then won't I be in
trouble? The color management would correct for the gamma and give me
the sRGB result. (Or is there something in the whole color management
process to account for this?)
