Yes, it is a 116" x 65" High Power, that works very well with the Pearl. These shots were taken after I did a calibration with no autoiris, but autoiris1 was used in these shots. I have not calibrated in autoiris modes yet. I also used cinema and gamma3, the latter after reading the Greg Rogers review indicating that (at least on his sample) gives a gamma of about 2.3.
Regarding screenshot technique, I've talked about this before, but the digital shots on my PowerShot 620 tend to enhance apparent contrast, usually by applying what looks like the equivalent of a higher gamma. So, much of my editing in Photoshop involves a bit of elevation of black level and minor adjustment of contrast. I don't usually touch color saturation. With my monitor at home this results in images that look more like those actually projected. Another key, I think, is to use a low ISO - I use 50, and manual settings to adjust for approximate brightness brightness, a tripod, and use of the delayed timer to remove any camera shake from button pushing.
