Author Topic: Muting eye/lens on Sony SRX-R320 3D Lens Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 09-01-2011 06:31 AM                     The absolute best on a Sony then would be a computer with 4k output. So what kind of 'best' are we talking about? No one knows what this specific machine will show on screen if a standard DVI input source is displayed through the 3D lens, because no one knows which formats have been configured on that machine. Connect and see, then decide what to do. - Carsten  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-01-2011 12:01 PM                     DVI content from a computer via a scaler through a twin lens setup looks excellent! Image is scaled up to do a flat presentation No complaints on this side why I'm not fretting about all of this.  |  IP: Logged Matt Skilton Film Handler Posts: 43 From: Bromley, Kent, UK Registered: May 2009 posted 09-02-2011 07:03 AM                        Thanks for the input everyone. I should perhaps explain the situation a bit more. Firstly, I've literally only just started working at this site so I'm still finding lots of things out. No one has been shown how to change a lens either because we've just started our Sony rollout and no one's fully made their minds up yet about lens changes (this is because our internal structure has changed meaning only one tech person per site). So changing the lens is not an option. The reason why I was concerned was because I've found some notes by my predecessor, which mentioned they did a show with the 3DL and the client wasn't satisfied due to the image on screen not being as sharpe as expected, so they tried muting the lens to improve this and then increased the light output to make up for the loss of light caused by the muting. I haven't been shown how to do this and was curious. I have since connected a Cine-IPM to our other 3DL Sony and connected it via the DVI output on the Sony and it looked good to me. However, the screen which will have the presentation is much larger than the one I tested so this may not be an accurate reflection. I'll change the Xenon because the current one would have done 400 hrs (it's a Ushio 4K XL) and will try and test it next week. Sadly I just done have the opportunities to do as much testing as I'd like as I have to run operational shifts too.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-02-2011 11:13 PM                     Do the bulb change, then do the test with your devices on that screen mentioned .. and you'll have to go from there...  |  IP: Logged Dominic Espinosa Phenomenal Film Handler Posts: 1172 From: California, U.S.A.

Also, muting an eye does not have a profound effect on light output. In fact I've only seen a very slight change in light output with an eye muted. Montey is pretty much on the money here, as usual. The difference in light output at the same level from 2D lens to 3D lens is < 1fL. I would also inform you that I have an SR220 running 2D thru 3D lenses giving 18fL at 50% lamp power; it won't go any lower than that! If the 3D lens was installed properly you should not see any bluriness in the image whether it is motion or static. Again, the type of content shown is very important here. By properly installed I mean the following: - The projector is as close to square with the screen as possible (side-by-sides cause issues here). - The projector is centered on the screen (some techs are not careful about this and rely heavily on electronic shift, which I find annoying) - Both lenses are zoomed the same (this is VERY important for convergence at the outter edges of the picture) - The convergence is set as close as possible by the hardware on the lens array. - *The software fine-tuning of convergence is done from inside the auditorium since it can be hard to see the lines from the booth.(I use a 100' crossover cable so I can sit in the room with my laptop). * The electronic convergence adjust is independent for each function memory so if it's good in SCOPE doesn't mean it's good in FLAT, DVI, or whatever else you set up. The function memory can be set up with any number of options to deal with aspect ratios as well. However. I did recently have a renter that had a weird bluray that just didn't look right in any of the ratios I could set up in software, thus I swapped the 2D lens on and set up a custom function memory, zoomed to fit her image. Looked fantastic.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-04-2011 06:40 PM                     quote: that I have an SR220 running 2D thru 3D lenses giving 18fL at 50% lamp power; it won't go any lower than that! ..what's wrong in going higher percentage in bulb use and putting more fL's on the screen (and with a silver screen which it wouldn't help ramping up some fL's in the first place), for you know, 50% power is cutting it a bit thin for bulb life in itself, esp for big bulbs. I'm usually shooting well over 20fL's on a silver screen in 2D mode ... (maybe, that's why that bulb popped on you last week or two - was it running a bit too low ..?) -Monte  |  IP: Logged Dominic Espinosa Phenomenal Film Handler Posts: 1172 From: California, U.S.A. Registered: Jan 2004 posted 09-04-2011 11:48 PM                     Monte, The bulb the blew had been at full power actually. Previously we were installing them and running at about 85% through the entire life of the lamp. I'm trying to keep the light output consistent over the life of the lamp but setting it for 16fL in 2D per Sony's recommendation. Each time you run the automated luminance adjust, it will teak the light output to bring it back up to the luminance value it had when you set it in SRX Controller. So if I set it for 16fL at, say 54% power the next time I run luminance adjust it will try to hit that same level by adjusting the current up. I thought I read somewhere that over-lighting the image is bad for some reason? Did I imagine that? Entirely possible...  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-07-2011 04:26 PM                     Maybe over lighting for Real-D is bad since that'll expose the "ghosts" - why the luminance is so low so we don't see the 'ghosting' as bad...then, the Real D box does the rest to do the "ghostbusting" process. ..but I have Barcos hitting between 20 and 30fL's and have a great picture on the screen with regular 2D stuff.  |  IP: Logged
