I want to go CIH, but have several reservations:
1. I want to use all the resolution of the panel, in both 16:9 and 2.35:1.
2. I don't want to use an anamorphic lens, because I don't have the money to buy one that won't degrade the picture.
3. My projector will probably have no lens shift, and minimal zoom range.
The above requirements possibly rob me of any way of doing CIH, except maybe the following way:
What if I were to mount the projector on a ceiling track ?. This way, if I want to watch 16:9 material, I push the pj forward on the track (to make a smaller picture), and when I'll want to watch 2.35:1, I'll push it backwards on the track. Actually, I can make the forward end of the track at a distance perfect for 16:9, and the backward end of the track perfect for 2.35:1, this way I will be able to easily and accurately switch between modes, because each mode will be the end of the track (this way I won't have to struggle with finding the exact right distance for each mode, everytime I switch).
Is it theoretically and practiclly possible ?, if so, what I are the downsides for this scheme ?.
