Having learned about Variable-Intensity sound-on-film recording, I went on to study the science of photography. One fact that impressed me was the so-called “resolution” capability of certain films used for aerial reconnaissance photography.
These ultra-high resolution films can resolve hundreds of thousands of lines per millimeter. Resolution capability is determined by photographing an object that has black lines alternating with white background in varying numbers of these black lines per millimeter.
In every square millimeter, such films resolve more than 100,000,000,000 (100 billion) discrete demarcations. Consider also that these demarcations differ from digital “pixels” in that both the black marks and the white background actually correspond to and portray details of the subject. Pixels, on the other hand, are interspersed with blank system noise which is not derived from the subject being photographed.
I have had the experience with some digital photographs that it pains my eyes to look at them. This was particularly severe when I used ebay to shop for long periods. I currently find that my eyes get sore when I watch broadcast (digital) TV. This never happened with analog photos nor with analog TV.
Digitalized images obviously correspond approximately or roughly with the real-world subjects they depict. But they are in fact artificial and alien distortions that pain the eyes because they force the mind to conform to something having no real and natural counterpart.
