back to an old topic of about a week ago. I bought some perceptol
today, but I suddenly realized that if you use it full strength it's
pretty expensive! What about using it 1+1?
Perceptol is Ilford's version of Microdol-X.
Microdol is often used 1:3. The results
of dilution are a matter of some debate.
To my eye MX works best at 1:3 - grain is
as fine as at full strength, but as the
grain is sharper it may look coarser.
Resolution is a very small ooch better
at 1:3 but the sharper grain makes the
resolution gain to appear much higher than
it is in reality.
And my pocketbook agrees: Microdol is best
at 1:3.
You can get times for Perceptol 1:3 from

If you can't find your film listed with
Perceptol look for times using Microdol.
