Hi All,
Well i'm after a formula to work out ft-lamberts of my setup, i've seen a few examples.
But then my BD801s is rated @ 900 ANSI lumens, which i know is a lot. (I'm sure it's much lower than that ??)
I know my screen gain is 1.0 and 72" x 54" in size.
How do i work out the ANSI - Ft Lamberts formula once i've worked out the corrected PJ ANSI output ??
Once i knew how to work out the formula, i could then do the formula with different gain screen materials.
Many Thanks
Cheers
