I've got an ASK BK!
What's a succinct way to explain to someone why standard movie theaters had no way of projecting a proper 1.37 or 1.33 picture in the years after the theaters had been retrofitted to show widescreen formats? I'm out of my depths here, but from reading posts on Home Theater Forum over the years, did it have to do with aperture plates and lens combinations? Am I getting warm?
Someone was asking about this, and wondered why they couldn't just "zoom in" the whole frame and employ masking? I'd love a short explanation that an intelligent layperson will understand, but I sure don't want to be spouting BS.
