Colour management annotation
I wonder why real absolute rendering, not to confuse with the ICC absolute rendering intent, is so often rejected in the thinking of many colour people. It is quite correct to point to viewing conditions. But arent these secondary? The first place are absolute ligthness and colour values, which can later be reinterpreted. If this relation to the physical capturing gets lost, the data is flatten out; much like a one shot flash light foto only covers a two dimensional representation of the three and four dimensional world. Introducing time and changing the point of view makes a real difference. I think the same applies to colour.
Sorry for me being a bit polemic, but I cant understand that information stripping, or better omiting, is the only valid way to create good photos.

Ok there are different paths open and the current one is shurely selected with reasoning by the ICC. Nethertheless people who like to ask questions to colour management systems run often in a difficulty to find inherent answeres. This can be seen as a flaw as it deprives cognition.
A simple example is: "I have calibrated my monitor, but when I measure Lab values from a colour patch on screen, they are not the same as the program says. Even though the measuring device is the same as for creating the profile."
