Over the weekend I performed a quick calibration with a lens aperture at -7, custom Gamma on Cinema mode I came up with with a max FL of 12.96. I would like to close the lens down but I feel it will be to dim. Those that have had the lens close what kind of FL where you readings?
Stop worrying about the FL readings and go by your own eyes as to what looks right to you for brightness, and then calibrate your projector
To me, my personal taste, I have calibrated my projector at -15 aperture and this is with a 150" screen (cinewhite material 1.1)
Aperture open more than -15 is just too bright for my eyes.
I set it at -15 and then calibrated my projector and could not be happier with the image.
However, please keep in mind that my HT is a bat cave, with 100% light control - all sides surrounding the screen are black for the 1st two feet, ceiling is flat black, walls are dark maroon/brown mixture, seating is black and carpet is dart grey.
Your HT environment makes ALL the difference to perceived brightness. If your room is not as dark, you may perceive your image as dim. Also, if your image taste leans towards glaring plasma like image, you will think the image too dim at -15.
However, if you have total light control, black/dark surroundings, and your image leans towards cinema experience (not plasma), -15 aperture, with even a large screen is plenty bright with the RS-4810
