If you are determined to crop the 235:1 image, the Lumagen or DVDO option makes the most sense. You get all the brightness with the least compromises. Of course, you are destroying the artistic...

I agree with all here in that all of these are expensive methods to achieve something that can be gotten for free just by zooming. If you look at the original post, though, he says he may possibly...

The lens you are referring to is a vertical compression lens. And yes, it is designed for watching 2.35:1 on a 16:9 screen. What it does do is utilize all of the projector pixels for 2.35:1...

13' will work but you will have more than a little pincushion. What lens are you using?

NO (all caps on purpose).

Vertical is fine, horizontal lens shift will seriously affect your image geometry.

Fantastic post.

I've seen the DolbyVision demo and you are right - it's a paradigm change.

Usually zooming also affects the centering of the image. In other words, a projector will not usually zoom evenly in the vertical - the image may shift up or down. Since I don't think this...
