Does anyone have a suggested "starting point" for development time for Tri-X (TXP) in Ilford Perceptol, either stock or 1:1? I have consulted the "Massive Development Chart" and come-up empty. I know I will need to do some testing, but I do not have any idea as to what time to start with.

Any input will be welcome.

Regards,
Darwin

From the look of things, Perceptol is a close copy of Microdol-X as ID-11 is a close copy of D-76. So look for some times for Tri-X 320 in Microdol-X and you should be pretty close, if not a dead on match for what you'll need to do with this film in Perceptol. Lacking any other information, that's exactly how I'd proceed with this.

Yes, Perceptol is Ilford's version of Kodak Microdol-X. Go to this Kodak publication and check out the processing instructions for Tri-X in Microdol-X

Thanks to all for the starting point. I knew that D-76 and ID-11 were similar. However I did not know that Perceptol was analogous to Microdol-X.

I've used the times listed for Microdol-X with this combo and found them to work well.

Try setting your film speed at 200 and dev. for 8.5 min. in straight perceptol at 68 degrees or setting speed at 320 and dev. for 12 min. at a dil. of 1:1 . this info. comes from the morgan & morgan darkroom book, which I have found very usefull .

when in doubt, I use the times at http://www.digitaltruth.com/devchart.html as a starting point.

I second the recommendation on the Massive Development Chart. Between this site and that, you pretty much have home and first base covered...

The chart doesn't have everything in every combination. But its a great place to start.
