Author Topic: Dunkirk - 15/70 Imax version Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 08-10-2017 05:40 PM                     Those 15/70mm presentations will always have that hot spot due to the silver screen that is used in IMAX houses for 3D. I bet the 5/70mm presentations looked tons better being on matte white screens.  |  IP: Logged Allan Young Expert Film Handler Posts: 125 From: EGHAM, Surrey UK Registered: Jun 2011 posted 08-16-2017 05:53 AM                     Caught this at the BFI IMAX in London last Sunday lunchtime. It was surprisingly busy for a movie that's been out for over three weeks; they're now selling tickets for four or five shows daily until August 31st. Thoroughly enjoyed the film. I must admit that I had suspicions that this could well have been Nolan's first big flop. I thought the subject matter might not have appealed much to audiences outside the UK. I also wasn't exactly blown away by the seven-minute excerpt attached to the 70mm IMAX prints of Rogue One. The image was way softer than the IMAX sequences in the likes of The Dark Knight or Interstellar. Dunno what the problem was with that but the image quality on display in the movie itself was truly spectacular. I actually got goosebumps during the first scene. Printing direct from the OCN probably helped significantly. Given the previous comments on here I had really low expectations for the blown up 5/65 footage but I didn't think it was that bad. There's a noticeable increase in grain and loss of contrast but I was expecting a lot worse. The one major image problem was with the skies. There were several vertical bands of brightness visible. Does anyone have any idea what might have caused this? Could it have been artefacts caused by the silver screen? It obviously wasn't normal hotspotting.  |  IP: Logged Bill Brandenstein Master Film Handler Posts: 413 From: Santa Clarita, CA Registered: Jul 2013 posted 08-16-2017 02:08 PM                     No weirdness in the sky areas reported elsewhere, nor seen by me, so I'd presume it was the screen. Rogue One was mastered in 2K, which would account for the poorer quality. I can't think of a better way to make 2K material look its best, however. (Trying to be positive. At least they're using film.)  |  IP: Logged Allan Young Expert Film Handler Posts: 125 From: EGHAM, Surrey UK Registered: Jun 2011 posted 08-18-2017 03:04 AM                     quote: Bill Brandenstein Rogue One was mastered in 2K, which would account for the poorer quality. I was referring to the Dunkirk preview attached to the 70mm IMAX prints. It didn't look nearly as good as the film itself.  |  IP: Logged Bill Brandenstein Master Film Handler Posts: 413 From: Santa Clarita, CA Registered: Jul 2013 posted 08-19-2017 01:25 PM                     Whoops! Sorry! But that makes sense too, as it would be 2 generations removed from the original camera negative from which the Imax prints were directly struck. (Gutsy move!)  |  IP: Logged Jonathan Smiles Film Handler Posts: 11 From: Devon UK Registered: Jul 2001 posted 10-06-2017 11:12 PM                        The issue with the BFI Imax is the screen, there is a uniformity issue with the silver coating at the top of the screen. I emailed cqo@imax.com, which goes to David Keighley who responded: There are uniformity issues with this screen that are noticeable with any light continuous tones, like skies of an image. We are aware of this issue and hopefully a new screen will be installed in the near future. Thank you very much for giving us your note as this adds to our database that it is bothersome to our patrons. END IMAX do respond so if you see issue email cqo@imax.com Jonathan PS my account profile is really old, I work in Production/Post these days. http://www.imdb.com/name/nm1211866/  |  IP: Logged Allan Young Expert Film Handler Posts: 125 From: EGHAM, Surrey UK Registered: Jun 2011 posted 10-08-2017 06:31 AM                     Thanks for that, Jonathan. I guess I'll be avoiding the BFI until they sort it out.  |  IP: Logged
