Looking for some advice guys…..
My bulb now has roughly 900 hours on it. I use the lamp on low due to the projector’s location, which is directly over my head. Iris is wide open. I use a Firehawk screen (2.35 – 96” wide). The projector is 12’ from the screen. I originally bought the Firehawk because I wanted to be able to have some ambient light in the room from time to time. I find that I rarely do this, but it is nice to be able to when the need arises. My room is completely light controlled and painted a very dark satin garnet red.
Last week the image just looked dark to me. I couldn’t make out shadow detail. I had this urge to grab the remote and bump up brightness. I drug the meter and laptop out and ran through grey scale, gamma and gamut. The grey scale had drifted considerably, so I zeroed everything out and started fresh. After a few hours, grey scale was looking ruler flat from 15 – 95. I changed my gamma curve this time with the handy gamma spread sheet. Gamma starts at 2.0 and steps up to 2.3 by 40 IRE then hits 2.5 at 60 IRE and stays there to 100.
I was pretty darn pleased with all that, for a couple days. Now I still have an urge to grab that remote and bump up brightness. Dark things in dark or mixed bright / dark scenes are just too damn dark. If someone is talking in a hallway, half that person’s face is visible, but the side of the face facing the shadows is complete black.
I’m toying with the idea of using the lamp in high mode, then re-calibrating. The projector noise will irritated the hell out of me, but I don’t see any options at this point. I’m also toying with the idea of calling Stewart and buying a different screen material to snap into my frame, but that’s a fair amount of coin to conduct an experiment.
Before I go through the trouble of re-calibrating with the lamp in high, I figured I’d ask you all for some ideas or tips.
