Question - the cartoon of the filtered scanner shows R,G, and B filters occupying about the same area over the sensor. Is that correct? Cameras have more green filters to coincide with our photopic response. Do scanners also have more sensor area associated with the green filter?

It depends on the quality of the scanner and its purpose. For example, high quality scanners used to digitize analogue film negatives use RGB scanners, so that they don't lose detail through Bayer RGGB Interpolation. Most standard document scanners use RGGB, I'm guessing because it's cheaper to manufacture.

This comment is critical but hopefully leads to real solutions So what IF those scanners are not cameras, I see this video showing any important difference We're gonna have to think about more than just light if we want to capture nothing more or less than the print Early teleprints might have been a good example, because I think those were drawn with inks that had special electrical conductivity- very simple to capture and send electronically Every print is probably going to have different chemical qualities, different electrical qualities, different topographical qualities, etc., and every print medium may need it's own special kind of scanner Thursday, September 7, 2023 CE, 16:35 EDT
