Time, a very general question: How and why was the 16:9 ever developed. Have something of "pixel ratio in the Movies" read. Is that so? And if so, can someone please explain?
16:9 is to the human eye, as a pleasant and harmonious in the perception / image, perceived as 4:3. we see her stop by the panorama, in general a larger picture, as top and bottom. probably synonymous for the reason that it gives panorama images.
