LOL! That is paraphrasing Dr Johnson I think! I must get that book. 

I think he is talking there about scanners acting as reflective densitometers.
I heartily agree there. One of the biggest problems is that of the incident
light. A proper reflective densitometer should have the source light
falling at 45 degrees to the print surface with the cell/CCD reading at 90
degrees. I don't think flatbeds do this.
