Mike, I hope you don't mind but would you have any advise for using with a rotary drum, i.e.., Jobo. Should I knock off 10-15 pct off the dev time as normal?
Thank you again.

The times at the top of the page are what I use with an old Jobo tank (2021 reels) on a unicolor rotary base.

Whitish fllakes in 510-Pyro

Hello,
Having only the ingredients and weights for the formula, I made a batch.
I just measured out the tea and added all solid ingredients befor mixing. At 150F all is clear and brownish. Upon cooling there are white-yellow flakes floating around. These settle to the bottom to form a clear,sticky layer.
What did I do wrong?
Thanks,
Bill

The 510-Pyro/Tri-X combination at EI 1600 produces surprisingly small grain for a two stop push. In addition it held the highlight detail and the shadow detail extremely well. A very effective two stop push is easily attainable with this combination.
