John, How's your filmspeed with Pyrocat? Mine was very low when I tested it with Fuji green.

John, How's your filmspeed with Pyrocat? Mine was very low when I tested it with Fuji green.
Yes,the film is far more vulnerable when wet than when dry.
Peter, I use the Carestream green and it seems pretty slow. I use BTZS, so I’m not sure how to translate it to an iso.
Thanks, John.
I took my first shot today with the EKTASCAN B/RA single-sided film. I seem to have some uneven development, and I hope to get a diagnosis. I would like to keep using Pyrocat HD, so my main questions have to do with presoak, dilution and agitation. Should I not presoak? Should I presoak longer? Agitate less? More dilute?
You should be able to see the problems in the upper left and lower middle. I couldn’t scan the negative (computer problems with darkroom computer), so I took a quick iPhone shot and inverted it.

I rated it at 80, at noon in overcast snowy weather. My development procedure, in smooth bottom 11x14 trays was:
1. 2 minute presoak with intermittent agitation in 70 F water
2. Pyrocat HD 1:1:100 @70F for 6 minutes with constant agitation for the first minute, then for 10 seconds every minute.
3. Water stop for 2 minutes with constant agitation.
4. TF 4 Fixer for 4 minutes with constant agitation for the first minute and every 30 seconds after.
5. Wash for 15 minutes in running water.
6. LFN 3 drops in 2 liters of water
7. Hang to dry.
Thanks in advance for any suggestions for me for processing the second negative of this shot.

PS. I did use the recommended red LED safelight, more than 6 feet away, pointed away from the sink.
I had similar results with a different developer. I've stopped using the film for that reason. Hopefully, you'll figure it out, but I lacked the patience.
Check your safelight; this may just be optical fogging of the film.
