First, I would like to say that I really appreciate Paul Montague's post. I think that it lays out a lot of useful info. However, it also raised one question for me:You say that - *Preliminary* findings indicate observers loose their ability to distinguish with digitized resolutions beyond 1024x1536 pixels.
I find this a bit hard to believe. There is a scaling problem here . I remember a presentation quite a few years ago by American Zoetrope that compared cine format film (approx. 70mm) to projection video.
First, I wourld like to point out that 35mm as formatted in slide cameras is generally unexceptable for cinematography for large-scale projection. People do begin to see the grains. at 1024x1536, I am sure that they would see the pixels. In the demonstration above, if the action was stopped, you began to notice the scan-lines. They weren't very apperent because of some tricky mixing. Indeed, they disappeared during motion, but you could detect them is stills.
