Hi Frederick, I did not realize measuring the light reflected from the projection screen would result in so little light incident on the instrument. But, in my view, it is nevertheless the better way to manage the color in this viewing situation. > Anyway, results are very good, and we didn't even make adjustement to the > projector (we also used low quality calibration/profiling). So, I'm sure > we can improve the result :o) This is very encouraging to hear. Thank you. Roger Breton
