This is about the resolution of most modern emulsions (unless you are using
super slow specialist films). I doubt the 19th centruy emulsions have
anything like that resolution. 19th century lenses are incapable of
resolving this well, anyway. Such a high resolution would only make sense
when scanning documents, or maybe paintings.
The resolution of most film images are much poorer than most people
realise.
