Back to the arguement about "Standard height to width ration". There is no standard. However, human vision do have more width than height, it is about 3:2, individual milage may vary. That is why the movie industry set this standard at the beginning and Leica adopted it since day one and evey body follows. TV has been using 4:3 for a long time. Movies has been using wide screen for a long time also. DH TV has moved away from 4:3. So what is the right ratio???
In the conventional motion picture format, frames are four perforations tall, with an aspect ratio of about 1.37:1, 22 mm by 16 mm (0.866 in Ã— 0.630 in)
. This is a derivation of the aspect ratio and frame size designated by Thomas Edison (24.89 mm by 18.67 mm or 0.980 in by 0.735 in) at the dawn of motion pictures, which was an aspect ratio of 1.33:1
VistaVision (used for a few years by Paramount Studios) was an 8 perf wide (film running sideways in the camera) format that was changed from sideways (using an optical printer) to conventional 4 perf for projection at aspect ratios between 1.66:1 and 2.00:1 By making a reduction print from the larger they got finer grain prints. When film improved VistaVision died.
So no motion pictures were ever shown at 1.5:1. Low budget wide screen was done by shooting 1.37:1 and cropping the picture to 1.85:1 with a projector mask.
Leica just took vertical 4 perf and changed it to horizontal 8 perf for their cameras.
