This one will be very dark .
Don't confuse MY PREFERENCE with my clients. I am the one that continues trying to defy the laws of physics by trying to preserve the view. Sue me but I like media rooms not theaters. Although I now fully understand the limitations of FP, there's no free lunches.
The Helene room before the porthole was measured at 815 when the colors were shot first even though the chairs are beige the room is long and narrow with navy walls. But that projector is a fluke it measured 860 in the west coast in a totally dark room. Probably after the port hole is 780.
This one Prometheus only measured 825 in the west coast. The room is freaking dark, with one double seal door 2 doors one after the other.
The wood is dark rosewood the ceiling and front wall and upper side walls is black gom, the lower sides and lower back is super dark navy, the chairs are deep wine, the divan (family bed is cashmere, don't know exactly there), it's very dark, but the screen is designed to ignore the walls ceiling and floor and direct the light at the audience.
This will be as dark as it gets from me probably.
But remember all the ansi cr. maximization effort is really for the MTF. It is not a clear correlation that MTF goes down linearly with ansi cr., my gut feeling tells me MTF can stay at maximum whilst the ansi cr may have taken a minor 15% hit for whatever condition.
Anyways please don't start picking on my marketing material to the customer, until every claim is proven it is just that.
