Attack of the Clones was shot in less than 1080p, at that point the camera (HDW-F900 camera) only did 1440x1080, and it was cropped from 16:9, as they didn't have an anamorphic lens, so that's 1440x817. Revenge of the Sith used anamorphic, so was 1920x817
Am I the only one who finds that anamorphic lenses create really distracting bokeh? The lens flares are always squished, and whenever the camera changes focus, there's this strange vertical stretching effect.
Since they were switching to new hardware anyway, why didn't they just make the CCD the shape they actually wanted, rather than relying on this weird archaic workaround?
Once you start delving into the science it gets really interesting; resolution is the least important part of the image. A high contrast ratio will improve the picture more than going from 720 to 1080 or 1080 to 4k.
