[Openicc] ICC support for HDR Images

IMHO what you need as a starting point is getting some experience in  
how ICC-colormanagement works practically. Get yourself a copy of  
Adobe Photoshop or use one of the lttlecms binaries to convert images  
from one device color space into another one. Do this with different  
profiles and different rendering intents and compare the results to  
get the idea, that is behind it.

Next, try to understand the mechanisms from a lower level. How do the  
transformations work internally. What is the Profile Connection Space.  
What kind of ICC-profiles do exist and so on. You will definitely need  
to read the ICC profile specifcation found at <http://www.color.org/>.
Antoher ressource to look at is the Apple website about color  
management <http://developer.apple.com/documentation/GraphicsImaging/Conceptual/csintro/csintro_intro/chapter_1_section_1.html 
 > and I think there is something similar on the website of Adobe  
Systems <http://www.adobe.com/>.

The Book "Real World Colormanagement" is a very good companion to your  
practical approaches.

If you understand how this works in general, you can then figure out  
the details of colorimetry, but I don't think this is absolutely  
neccessary for ICC-support in HDR-images.

best regards
