pull down interesting. I don't know how factual or relevant it is, but it does give some clues where the 4:3 ratio of old TVs came from, which I found interesting. This is the "postage stamp" format?
I've been paying a good bit of attention to the aspect ratio of movies lately. I don't know why. But I've been impressed by the lack of variance (which could just be my own lack of variance in picking movies to watch, not movies in general, IDK). Nearly all movies made in the last few decades seem to be 2:39:1, with a few at 2:35:1 and fewer still at 2.4:1. What are the reasons for these small variances in aspect ratio?
I can't remember the last movie I saw in Super-35 (1.58:1), which is very close to the golden ratio (1.58:1).
Then again, I just got a copy of 2001 A Space Odyssey on BD, and it's in its original 2.2:1 aspect ratio (non-anamorphic 70 mm) which is very close to my favorite panorama aspect ratio of sqrt(5):1.
