I'm pretty new to the whole home theater thing and I am in the planning stages for my first (and hopefully my last) build. I may be a little confused about the differences between projector image stretching and using an anamorphic lens to achieve a 2.35:1 screen size.
If I understand correctly, using the anamorphic lens converts a 16:9 image to a 2:35:1 image. So if the original movie is "squashed" into the 16:9 frame, the corrected image will have the correct aspect ration. In this method there is no loss of vertical resolution. If this is the case, how is the 2:35 image stored?
In the projector image stretching method, the projector basically zooms the 16:9 image containing the black bars and 2:35:1 image to fill the wide screen. If this is the case, then there is loss of both vertical and horizontal resolution. If this is actually how it works then is the loss of resolution noticeable? Or, is there some clever digital technique that preserves the resolution of the source image?
My apologies if this is a FAQ. I've tried to find the specific answer but have been unsuccessful.
