If there is a lot of dissolved silver in the final fixer - and thus dissolved silver in the print - there will be staining. The second fixer bath has to be really fresh. -- Nicholas O.

You're right, my usual procedure is to wash the prints for 5 minutes in running water (while I'm exposing and processing the next sheet) and let them stay in a sink until the end of the session where I tone them all one after the other. With the same F-9-like fixer that looks bad to the iodide test, I tried to: - put the print directly from the fixer to the selenium -> staining - put the print from the fixer to a short (10 seconds) rinse to selenium -> much less staining but still some - wash the print for 5 minutes between the fix and toner -> no staining I've the impression that Ishould be able to tone the print after a shorter wash than 5 minutes but was a bit short of time to test it this week-end. The idea being to put the wash and toning in-line with the previous steps and letting only the final wash to be done at the end of the session. Claudio Bonavolta http://www.bonavolta.ch
