I am very curious about contact printing paper sharpness. Since I do mostly 35mm work and know some limitations of paper sharpness, I assume there are preferred papers for contact printing to obtain the sharpness benefits of large format. I see posts that seem to say there are obvious print quality advantages to an 8x10 contact vs a 4x5 enlarged to 8x10. With slow emulsions grain should not be an issue - so I'm trying to figure what the differences are. Could it be that thinner paper emultions do better? When I last used my 4x5 some years ago I processed B&W although much of it was Kodalith or Kodak line copy 6573. Just before I put my 4x5 away I started doing more "normal" landscapes etc. and I enlarged 2x3 sections of the negative - the largest my enlarger would handle. My 35mm work is only color and occationally I would like to shoot again with color in the 4x5.
