Has anyone used this on fiber paper? What kind of results did you get? I used it the other night on a fiber print and again on an RC print. It did a good job on the RC print, nice even fairly subtle sepia tone, but the FB print never really came back from the bleach stage: it's literally a ghost of its former self, albeit a brownish one. The effect is interesting actually on that particular print, but nothing like I wanted or expected and nothing like a properly sepia-toned print and nothing like the RC print with the same solutions! I bought the stuff bcs. it said it was good on all papers. Any experiences here to inform my confusion?
