[argyllcms] Re: Spyder 3 pro

I am very grateful for this advice. I am starting to understand new concepts.


Hmm. Mine is a Spyder3 Pro, and it works fine. Please mail me a trace
for "spotread -D5 -a 2> log.txt" and then hitting the space
bar and then quitting.

I have done this and attached the file.  Paragraph of note:
"Requested ambient light capability,
and instrument doesn't support it.
Will use emissive mode instead,
but note that light level readings may be wrong!"

I am trying to calibrate an LCD monitor, Samsung F2380, which has particular problems with 'black crush' - displaying dark shades of grey as blacks. My monitor's factory settings are brightness 100 and contrast 75. I read in the
argyll documentation it's often best not to change these, so haven't.

Loosing black levels is not necessarily a problem with calibration or profiling, but a lack of suitable gamut mapping. See <http://www.argyllcms.com/doc/CrushedDisplyBlacks.html>
I have read-up on this and now understand colour spaces, so that's a start. I will re-profile again tomorrow using the details given on that page. It looks like the best my monitor will do is sRGB, but at least it says it can do 100% of that.
