Hi Rinus<br>
Yes i have reluctantly come to the same conclusion. Years ago as a
visual arts student ( Dip.Fine Art ) they taught us a bit about how
humans see color. It was something of a revelation to me to find out
that every <b>person</b> has their own color perception profile,
genetically and experientially determined.<br>

All,
<br>
<br>
A few thoughts about color management to share. Moving from
windows to Ubuntu brings enough changes to workflow to need a lot
of adjustments and a heap of dimes for tests prints.
<br>
<br>
Why color management is doomed to fail:
<br>
Every surrounding has its own light quality and if we talk about
outdoor photography the light changes continuously. Your lens does
some little tricks with the light before it is projected on your
sensor, which does its own tricks on the light. The camera
manufacturer applies some profile to make the best of it. Then you
export it to your computer, which displays your picture according
the ideas of your your screen cards manufacturer and the profiles
used at that stage and then forwards it to the screen which
displays it in his own particular way after using another
profile. The image you see highly influenced by the light
conditions of your room.
<br>
Now you start to optimize it with your photo manipulation
software, which might apply another profile as well. After that
it goes to the printerdriver, another profile comes in before
sending it to the printer, and again some profile comes in, and of
course you selected your paper which is again a profile.
<br>
Now you have a picture, and if in all those mentioned steps and in
the steps I forgot to mention everything went well, and you would
look at it at the same light conditions as you shot your photo, it
should at least look a bit like reality, although not perfect
because the paper can not reflect the colors and contrast of
reality.
<br>
<br>
This is the goal of colormangement, but we realy need a lot of
help of the lord, to have the output look like the input. Besides
of that, in most occasions we would not be to happy if the
pictures looked like reality. Out of the context, people will say,
¨oh no that sky can never be that red¨, or ¨the water can never be
that blue¨. If you shoot indoor with usual light, and it has been
reproduced very well we will experience the pictures as much to
yellowish and so on and so further.
<br>
<br>
A better way:
<br>
Try to set everywhere in your workflow same color profile. This is
hard, settings pop up or hide in so many places!
<br>
Make a room where the light conditions are optima forma according
final exposing conditions.
<br>
Compose a test print from different pictures, all colors, shadows,
highlights should be represented as much as possible. Print and
view. Make all needed adjustments in your photo management
software and print again and view. And so on until you have your
best possible print.
<br>
<br>
After this calibrate your monitor so that it relects your print in
the best possible way.
<br>
<br>
From now on trust your eyes and WYSIWYG.
<br>
<br>
Thanks for reading and let me know what you think.
<br>
Best regards,
<br>
Rinus
