I wonder if a good comparison in resolution ONLY has been made comparing film to wet plate
While we are at it let us include historic, current and any hand made Dry Plates
but only LF sizes, please

I watched a Topshit Photography video where he said that the collodion and silver make for a nearly grainless image.
Something about using molecules instead of film grain, or something to that effect.

Don't have any resolution data but this was an informative test

I have found the tins I make are indeed grainless. I haven't been able to make any meaningful comparisons of resolution because I shoot wet plate with 19th C. lenses and film with modern Copal lenses.

Wet plate still clumps into grain, but grain is generally proportionate to speed, so yeah, it's small. But looking for grain on a tintype is like looking for grain in a contact print. Gonna need a microscope...
It would be fun to see a big print from a 4x5 wet plate negative beside a similar print from 4x5 film, same lens on the camera.

Do you want science or subjective impressions? For the latter, I'll say "wetplate is sharper than most film". For science,
"The collodion layers have very low granularity and are comparable to microfilm emulsions. Intensification results in higher granularity."

"Even if fine grained, wet collodion process was definitely not infinitely resolving."

Some of the big scans on Shorpy from 19th century appear grainless. I have not personally run into much grain scanning an ambrotype or tmax 400 with the Epson scanner but I'm not scientific about it.
I may be wrong but I think Daguerreotypes are the highest resolving process.
Should have quit while we were ahead...
