hi just another thought on this: yes, for professional work the ambient light should be constant. But to say there is no logic in this, i don't understand. I think that many non-professional users would benefit from this. It would create a more 'streamlined experience' (not my words) ie if you design some material to be printed on your monitor looking quite warm colored, it wouldn't pop out of your printer entirely blue due to the difference in color temperatures..... josvanr On Sun, May 29, 2011 at 3:30 AM, Roger Breton <graxx@xxxxxxxxxxxx> wrote: > That's a marketing idea of monitor's manufacturers.
