Author Topic: 14 footlamberts sucks Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 09-20-2009 03:20 PM                     It was nothing special actually. Christie SB projector, CXL60 lamp, Harkness matte screen, screen is something like 28 feet wide. I haven't done a shootout personally between Christie and Barco, but these Christies put out a hell of a lot of light and it is magnificently flat across the image.  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 09-20-2009 03:49 PM                     So about a 10meter wide screen. Not really that big.  |  IP: Logged Mike Olpin Chop Chop!

Waiting for Mr. Kinoton to enter and tell us all his film projectors do better.....  |  IP: Logged Demetris Thoupis Phenomenal Film Handler Posts: 1240 From: Aradippou, Larnaca, Cyprus Registered: Apr 2001 posted 09-20-2009 04:45 PM                     Actually that screen if it's the size Brad mentions is more or less 10 meters x 4.25 considering common height for flat and scope and considering that is the scope width he gave. A screen like that needs no more than 2.5K and that is a lot for 2D application. If you are trippling the light output of course you will get more fl Brad. The screen is small for the lamp power you are using for 2D.

I also don't think you will find that film running the same lamp would put out that level of light, hence my comment that it was nothing special as far as a "secret trick" for 2D and why I posted the result in the first place. Bear in mind besides the 3D looking extremely good (noticeably better than the 4-5'ish footlambert installs), the 2D at that light level was nothing short of spectacular, so if burning a larger lamp yields that sort of amazing result, so be it!  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-20-2009 08:19 PM                     LOL, Brad... I had two customers tell me that too. Then right off the bat they were running that National Geographic World film in 2-D at 48 foot lamberts. I'd bet those kids got their retinas burned!!

No, I certainly don't hate digital, as I have mentioned a number of times that I was very impressed with even what our dual AV Barcos can do in stacked operation. Because I love film doesn't me I hate digital; because I loved IMAX, doesn't mean that I can't be objective enough that in another thread I was quite clear when said I thought their dual 2Ks gave a very impressive picture -- not 15/70, but certainly a cut above standard digital rooms. As far as quote: Brad Miller you need to see it before you make such a foolish statement. How could you miss that this was the same tongue-in-cheek as Mark's quote: National Geographic World film in 2-D at 48 foot lamberts. I'd bet those kids got their retinas burned!! Me, they need sunglasses; Mark, they get their retinas burned. Same thing.  |  IP: Logged Danial Simmonds Expert Film Handler Posts: 107 From: Kota Damansara, Selangor, Malaysia Registered: Jan 2008 posted 03-22-2010 03:50 AM                        Just out of curiosity, was the 3D Wheel down and one of the glasses placed infront of the color/luminance meter? I ask because last time when i was asked to check light level for 3D by for Avatar they gave me the instruction to measure with 3D Filter down, Left Eye or Right Eye 3D glass infront of the meter On a screen about 11 meters wide and a throw distance of 18 meters, matt white screen, CP2000S i got only 2.8fL... Using a minolta CS200...  |  IP: Logged Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 03-22-2010 01:19 PM                     quote: Demetris Thoupis Actually that screen if it's the size Brad mentions is more or less 10 meters x 4.25 28 feet is about 8.5 metres.  |  IP: Logged
