True, in the long run Dolby is the way to go when it comes down to cost.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 07-05-2012 04:45 PM                     it's indeed a problem, particularly for big multiplexes. I cannot think of cinemas recycling and sanitizing 3D glasses every day. But the silver screen is not an option either. If I had a cinema and really wanted the 3D (unlikely) I'd go for XpanD. Dolby is good, but glasses' quality consistency is simply not acceptable.  |  IP: Logged Olivier Lemaire Expert Film Handler Posts: 118 From: Paris, Ile de France, France Registered: Jan 2010 posted 07-05-2012 04:51 PM                        In France, Silver Screen will be "prohibited" in the next 5 years (at least if you dare believing what a public sector entity may declare 5 in advance...) : http://www.today3d.com/2012/03/france-kills-silver-screens-votes-out.htm We will see that in 5 years...  |  IP: Logged Peter Castle Expert Film Handler Posts: 220 From: Wollongong University, NSW ,Australia Registered: Oct 2003 posted 08-14-2012 06:33 AM                     I was looking for a topic involving screen brightness so as to avoid starting a new one and found this. We're about to update our Series 1 projector to Series 2 and are increasing lamp size, mainly to accommodate brighter 3D. The problem is: Can a screen be too bright? With 2D advised to be 14fL, and 3D seeming to head towards 6fL, can screen brightness be too high? How do you determine what brightness to run at? By sight, or by meter? Any experience out there with high brightness screens?  |  IP: Logged Bajsic Bojan Expert Film Handler Posts: 190 From: Ljubljana, Si, Eu Registered: Aug 2008 posted 08-14-2012 06:49 AM                     We've had the issue of a screen being to bright here (80ftL) and what i can say is that: -colors are a bit shiny, -image looses some contrast -black is not black but a shade of gray The post production guys that come here often with their test material thought it was too bright especially when running same material side by side with 35mm. We eventually went from 3kW bulb to 1.2kW and changed out our 1.6 gain screen with matt white. Got 14-16 ftL and we're happy. When setting up for the first time, use a spectroradiometer for color reproduction and luminance measurements.  |  IP: Logged
