The image on film made by an SLR camera is not... dots. It captures the image from light (which has no stepped gradations or dot) using optics, and duplicates at whatever the film density is, but I don't think we can just hand wave away what is going on at literally the molecular level on film with 1-bit depth and say it is halftone, even if technically is similar, in theory, at that molecular level. This ignores the scale of the vast chasm between macro world and Interspace. I'm not clear on resolution, but I know with color, 24-bits is sufficient to be known as "true color." I recall when I finally got a 8-bit graphics card for my Mac II c.1991, having lived with 1-bit monitor for 2 years and seeing 256 shades of gray on it felt somehow miraculous. But since then, I have seen more than 256 shades of gray, and I think many can tell the difference between 8-bit and 16-bit grayscale. What I mean is, whatever 8-bit grayscale is, it can't be "true grayscale," if such a thing existed.
