30 Minutes in Rodinal 1+25 ???

Hmm I never heard this before.
We use 10 Minutes at 20 deg. C for comparison tests but the final product (because it is higher in effective speed) might end up between 10 and 13 minutes.

The First Coating comes best at about 11 Minutes.

Are you sure your Rodinal is OK ?

Best regards,
