About Calibrating HDR-projectors on Calman

[Gregg Loewen]

use the HDR work flow.
Most likely do not adjust the black level and white level controls.
measure peak luminance and then enter the screen offset.
Do 2 point white balance and EOTF adjustment.
Consider multi point white balance.

Do you mean that I have to consider the maximum luminance firstly in calibration before adjusting anything? To adjust EOTF, I have to consider White level and Contrast Enhance like these functions?

1.
According to the Calculation way to approach 1000nits, then the measured EOTF is usually likely to be over the Calman EOTF grapgh? Is this normal?

2.
Please explain the below that you said.

” IF PEAK LUMINANCE IS AROUND 1000 NITS, then 50-65% will be at 400- 500 ? NITS (guessing ). ”
