This brings up a related question. ID-11 and D-76 are often said to be the same developer formula. But Ilford gives different times for ID-11 and D-76. For example, for HP5+, Ilford suggests a time of 13 min for ID-11 1+1, but 11 minutes for the same dilution of D-76. Weirdly, for FP4+, it suggests a longer time for D-76 than for ID-11. That suggests to me that they aren't exactly the same formula.

"Shannon Stoney" <shannonstoney@xxxxxxxxxxxxxxx>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 http://www.digitaltruth.com/devchart.html If you can't find your film listed with Perceptol look for times using Microdol. == Nicholas O.
