Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 12-08-2011 01:02 PM                       Similar in concept to Dolby 3D.  |  IP: Logged Mark J.

Glasses/filters similar to Dolby. Louis  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 12-08-2011 09:27 PM                       Panavision also works with D-Cinema as well, although I don't know if it has been implemented that way to date.  |  IP: Logged Mark J. Marshall Film God Posts: 3188 From: New Castle, DE, USA Registered: Aug 2002 posted 12-09-2011 06:05 AM                    Interesting. I while back I asked if Dolby 3D filters and glasses would work for film and the answer was "no" because the filters are aligned with the red/green/blue light that comes out of the digital projectors and since film uses yellow/magenta/cyan they wouldn't work. It sounds like you're saying that the Panavision system glasses are aligned with the yellow/magenta/cyan of film. If that's true, how would they work for digital projectors' red/green/blue light?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 12-09-2011 06:31 AM                     I believe the Dolby system would work...BUT you would not have it color balanced and with no way to color balance it. As for Panavision, they do not create a dramatic color shift, it is done with comb filtering. It is entirely possible to do the Panavision system with 2-projector 3-D too. Barco, now has a Panavision option for their projectors (Barco supplies the mechanism for their projectors on the Dolby/Panavision systems)...I presume Panavision has a rig, similar to Dolby's for other brands of projectors...except Sony, of course. The Panavision and Technicolor 3D lenses are identical except for the filters so single lens 3D is also possible on film. -Steve  |  IP: Logged Kevin Fairchild Expert Film Handler Posts: 125 From: Kennewick, WA, USA Registered: Oct 2008 posted 12-09-2011 12:12 PM                     Ummm..... where would you even get content? And have fun making sure everything is spliced just right on both prints.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 12-09-2011 12:19 PM                     Content? Any of the Technicolor prints will run on the Panavision system. As for 2-projector prints...those too are available if you are on the right list...they would be of classic titles like Dial-M for Murder and such. -Steve  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 12-09-2011 01:07 PM                     I think he might asking about digital content (based on how the discussion drifted and all) and I would assume that regular 3D dcp's would be used but I could be wrong.  |  IP: Logged Jack Theakston Master Film Handler Posts: 411 From: New York, USA Registered: Sep 2007 posted 12-09-2011 02:41 PM                     While we're on it, has anyone had experience with PAINTING your matte white screen silver? Are they all crap or are there people who can really do this properly? Is it possible to adapt the Panavision or Dolby systems to 35mm projection?  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 12-09-2011 03:12 PM                     Panavision works with 35mm and digital.  |  IP: Logged
