I don't know what is in Acufine. Microdol-X and Ilford
Perceptol are identical. They use common salt as the fine
grain agent in a low activity Metol developer. Both yield
finer grain than standard developers when used full strength
at the cost of about a stop of speed. I have started to use
Perceptol as my standard for 35mm 100T-Max, the grain being
comparable to the late, lamented, Kodak Technical Pan in
Technidol. I have no idea of how well it would work for the
Maco film but its worth a try. I doubt if any practical
developer will give you finer grain.
When diluted the extra-fine-grain property is lost. At
1:3 either developer will deliver full film speed and about
the same grain as D-76 but with significant acutance
effects.
