THE CHANGING SHAPE OF CINEMA: THE HISTORY OF ASPECT RATIO
1890 Edison 조수인 Dickson에 의해서 4:3 비례 탄생. 4:3 ratio mimics human eyesight visual angle of 155°h x 120°v, that is 4:3.075, almost exactly the same. 확실한 이유는 모른다는 설.
In 1090 the Motion Picture Patent Company declared that 35mm film with Edison perforations, and 4:3 aspect ration with an image 4 perforations high as the standard for all films that were to made and shown in the US. This setteld it-making film and projection ubiquitous across the US.
1950년대는 widescreen war였다. 이것은 TV의 등장으로 인해서 가정 내에서 보는 것이 일반화 되면서, TV가 할 수 없는 극장만의 기능이 무엇인가 모색하면서 나타난 현상이다. 즉 scale이 극장에서 제공할 수 있는 강점이라는 결론이었던 것.
Multicamera/ multiscreen system 또한 1950년대 유행
There were a lot of problems with shooting and projection three cameras. .. The problem with Cinerama was it was expensive to shoot and expensive for theaters to project.
1953 Paramount first FLAT widescreen studio film.
cinemascope / vistavision / Todd AO / MGM 65 등 정말 많이 필름들이 생겨났는데 모두 aspect ratio가 달랐다.
then where did 16*9 come in??
for that answer we have to turn back to TV. 16×9 was the geometic mean between 4×3 and the 2.35 the two most common extremes in terms of aspect ratio. This means that a images of either aspect ratio would have relatively the same screen area when properly formatted in 16×9 with letter boxes.
And so, out of a compromise, the 16×9 aspect ratio was born and it would become the default widescreen aspect ratio for all video products from DVDs to the new UltraHD “4K”
