I was trying out some Ultrafine RA-4 paper the other night. I'm getting this result: Any idea what's causing the overall orange stain? I'm processing at 95deg F using Kodat RA-4 chemistry. The same negative pronts fine on Kodak paper. The Ultrafine is re-branded Agfa paper and claims to work with all RA-4 processes. I think this is some kind of processing issue - not a filtration issue as the borders of the print are also orange even though they have no exposure.
