This thread is for all members who have Constant Image Height projection, to show off their theatres..
I'm sure there are few out there, so lets have a look (just out of interest) at what your set up is like..
I have a website with a bunch of photos of Anamorphic lens installations. I mean no commercial intent so I am trying to post a link that leaves any other links out and goes straight to the photos:
Edit:
Well, after looking at my photos link, I figured the mods would see it as advertising, so I removed it. If a mod want's to pre-approve it let me know. I think the members would like to see the samples of other's installations, but they are on a commercial site.
It's too tedious to link each picture and remove any that might be construed as commercial individually.
Nice job Mark. I was just talking to my wife this weekend about redoing the lighting in the theater. Right now I'm working on moving my Denon AVR988 to the bedroom system.
Hi Prof, they are actually Bipole, so no chance of phase errors between speakers. I do however want to change them out for dipoles as I think dipoles will work better in the small room.

Thanks TwisterZ. The lighting is the most simple and cost effect thing I could find. It is just an LED rope light, yet works well to provide low level ambient light.

I have Dipole on sides with direct radiating in the rear. Currently the rears are at THX recommended real close, on either side of my projector about 18". I prefer having them half as wide as the fronts.
Tri-poles are good at reducing the null effect at the listener position that you get with Dipoles..
With a front firing woofer and the forward and back firing Mid/highs, you get a more encompassing surround sound..and I've never felt the need to go to 7.1..
I took a look at the M&K tripoles a while back. The idea intrigued me, however at that stage, it would have meant a total redesign. The new surrounds will be something new, however I get to simply recycle the drivers I currently own.
7.1 is amazing, especially fully discrete stuff on BD. THX Cinema 2 processing also does a wonderful job of 5.1 and 5.1EX program.
That's a nice size screen Simon...You forgot to mention that it's an AT screen!
Do you have any other shots taken from further back, to get an idea of the room overall?
Hi All here is my DIY 2:39 130" screen sorry about the poor quality its from my mobile. when i can work out how to turn the flash off on my camera i will post a clear pic up but for now you can see the size but not the quality.
If the projector you have or are looking to buy doesn't have auto AR, then an anamorphic lens is a good alternative to manually zooming for the different aspect ratio's..
i've heard those are pretty expensive. as far as manually zooming, what exactly does that involve. would i be simply adjusting the lens by turning it somehow. just curious the amount of work that would be needed when someone talks about manually adjusting
On my projection system, it takes less than 30 seconds to adjust between aspect ratios. That includes adjusting the zoom control ring, vertical lens shift knob, and moving the drapes for masking. Focus is stable when zooming on my projector.
Vertical lens shift range will vary, depending on projector placement. None at all is needed if the lens is located perpendicular to the vertical center of the screen.
The wall behind the screen should be painted black or very dark. Black bars on letter boxed Blu-ray Disc movies will project onto the wall above and below the screen, which can be distracting if the black levels on the projector are not good enough.
The lower cost JVC D-ILA projector model still has excellent blacks, plenty of motorized zoom and shift range, plus lens memories. Last I checked, the less expensive Panasonic LCD projector is similarly enabled. The Epson line may also include a candidate.

When you manually change AR's, you would select 2.35 on your remote ( if you're changing from 16:9) and manually zoom the image to fill the screen..and sometimes you may need to refocus..and it's not always easy to just fill the screen and not lose some of the outer image onto the borders..
Generally it's a pain..and particularly if you need to change from 16:9 to 2.35 and back to 16:9 AR during a movie night..
There are more and more projector makes that are now including auto AR's..My last projector has that facility and I'm now able to do away with the anamorphic lens..
Room is 11'-6" x 13'-6".
Have a 9' wide 2.40 curved AT masking screen with Screen Excellence EN4K fabric.
Projector is Sony VW600ES
A-lens is Prismasonic HD6000 with powered slide
Viewing distance is 9'-6"
Room has black walls, black ceiling and black floor. Have black velvet curtains from floor to ceiling on side walls from screen wall to seating. Will see about hunting up pictures later, since the pictures are stored on another computer.
I have a Panamorph UH-480 lens and a Panasonic ae8000 projector. I am trying to figure out for a 150" 16x9 image if i am better off putting the projector as close as possible to the screen or leave it on my back wall shelf which is about 19' from the screen.
I am also thinking of making a sled that would allow me to adjust the projector distance...using 2 linear slide 6' long tracks, and 4 bearings. These would run from the rear wall 6' toward the screen, so I could even get a different projector down the road without having to drill more holes in our ceiling. Once the rails are installed I would attach a plate to the bearings and mount a short piece of pipe to suspend the projector a few inches (or use a thick platform). I would then add 4 more bearings and run a pair of 2' long rails running parallel to the screen for mounting the lens. By doing this I could slide the lens out of the way too. The advantage I have now with the lens is I can go from 180" diagonal (scope) without the lens to 195" diagonal (scope) with the lens. Last night i watched Avatar with the lens mounted on a shelf, and I was blown away with the clarity, and the additional 15" of image.
