Problem solved.  |  IP: Logged Peter Castle Expert Film Handler Posts: 220 From: Wollongong University, NSW ,Australia Registered: Oct 2003 posted 10-02-2012 07:45 AM                     What do you mean, John? We use shutter glasses. There is nothing in front of the projector to leave there.  |  IP: Logged Peter Castle Expert Film Handler Posts: 220 From: Wollongong University, NSW ,Australia Registered: Oct 2003 posted 10-03-2012 04:21 PM                     The figures are in. I did not indicate to our audience that there was any change in our presentation for the screening last night. The only comments were positive ones, so 25fL isn't considered too bright by regular patrons. I myself certainly noticed the grey areas outside the picture area on flat but our audience didn't. So we'll go with it as is. It will be interesting to see what brightness we get on 3D.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 10-03-2012 06:26 PM                     So this the 7kW bulb?

I personally cannot stand a dark picture. I do love a 18-20fL picture over the standard 14fL. Over that level black level becomes too high and - depending on the movie of course - the picture washes out a bit. In your setup, I wouldn't be too worried about it. You can set a different light output using different "titles", you can run your lamp at 7K on 3D, and at 3.5K on 2D, even though this is not very good for your lamp. It shouldn't be a problem to run your lamp at 6K in 2D though. Is the "flare" you're seeing maybe caused by the Silver Screen (assuming you're using a Silver Screen?)  |  IP: Logged Peter Castle Expert Film Handler Posts: 220 From: Wollongong University, NSW ,Australia Registered: Oct 2003 posted 10-04-2012 06:00 PM                     Our 3D is now set up. We are running both 2D ratios (flat and scope) on setting of 70%, as that's the lowest it can be. 3D scope we have at 100%, 3D flat at 90%. We couldn't seem to measure the brightness level of the 3D as simply as the 2D, so we just did it by look - it looks great. So, while the 2D is a little bright, the 3D is the best I've seen. No silver screen, shutter glasses. Using a Harkness tester. One side effect is that, in the past, we could mix 2D and 3D trailers together in one playlist, and patrons would leave their glasses off for the 2D. Now the 2D part is way too bright, but looks OK with the glasses on.  |  IP: Logged
