So I've noticed there is a ton of reviews about the performance of the CineGrey5D in ambient light conditions... I have not however heard much about its performance in dark, or near dark conditions. My room is mostly light controlled, with blackout curtains. The only light visible in the room is light through two double doors (from the side) which have frosted glass allowing diffused light to pass through during the day.
I do the majority of watching in the afternoon into the evening. I would say about 70% of the watching will happen when I have an almost completely dark room. However I want to be able to watch during the day, when there is ambient light from the glass doors. This lead me to look into this grey screen material.
So how does the CineGrey5D do at light controlled rooms? Is color accuracy lacking vs a white material screen?
