Author Topic: Real D causing focus uniformity error Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 01-23-2012 11:21 PM                     I have a theatre whose employee states that the image from our Barco projector is in focus with no devices between the light output of the lens and the screen; however, when the Real D unit is slid into position in front of the lens, the lower half of the image is out of focus. The Real D unit is left in front of the lens all the time while a 3D movie is assigned there. So, when the pre show comes on, it goes through the Real D unit and it is here that the focus uniformity is problematic. Does anyone know if there is an adjustment for such a problem? This is a Barco series 2 projector with a Real D 3D unit that slides back and forth on lateral rails into or out of the lens path. We got one of those slam-bam installs without any technical training what so ever on the Real D 3D units.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 01-24-2012 12:41 AM                     Sounds like nobody did any internal adjustments to align the image to the Real D "XL' unit. Or, somebody got into the adjustment screen and messed with the settings. Better call them back and do the job right. How does 2D playback look - pull the XL unit aside when the preshow is going and see how that looks...  |  IP: Logged Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 01-24-2012 12:26 PM                     Monte: quote: Eric Robinson the image from our Barco projector is in focus with no devices between the light output of the lens and the screen from above. Thanks for your input. Presumably it looked good after the install, but is now out of whack.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-24-2012 03:58 PM                     Is it the normal ZScreen or the XL? - Carsten  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 01-24-2012 10:09 PM                    How does the focus look with the RealD 3-D glasses on? It is possible to knock out the mirror adjustment if you push the RealD XL unit to hard against the stops. This can cause 2-D content that is projected through the XL unit using a non-3-D output, such as the pre-show output, to appear soft.  |  IP: Logged Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 01-25-2012 12:10 AM                     This is an XL unit. Apparently this is only affecting the preshow. The 3D feature following has good focus. Nora from RealD sent me a manual so I probably just need to RTFM. Thanks for the tip on knocking alignment out with rough treatment.  |  IP: Logged Stefan Vogels Film Handler Posts: 48 From: Aarle-Rixtel, Noord-Brabant, Netherlands Registered: Jan 2010 posted 01-26-2012 04:59 PM                     The RealD XL unit has 3 settings which you can change. You can adjust the size of one of the images, you can allign left / right and up / down of the images. There's also an locking mechanism which needs to be loosened before adjusting ! Use the cross Hatch test pattern to allign. Best Regards  |  IP: Logged
