looks all right. Only be sure to have no foreign reflection on the screen.
When I tried to spot meter a screen I found its black be far too black for
letting the spotmter to work. So the 18 0ray is a good idea. Of course you
know the 18 0ray should be a 50 0ray from the monitor point of view...
You could spot the white and add 2.5 stops just the same. The screen is
far contrastier than nature, you have to bracket a bit. A tele is a good
idea also for lessen prospectical aberration.
