The only other developer I’ve used with the JOBO SilverBase process is Adox’s Silvermax with Fomapan 100, Kentmere 400, Rollei Superpan 200 and Delta 400. Didn’t see the issue with any of these films. Silvermax does tend to have a longer development times though. With Rodinal at 1+25 I’ve seen it both with TriX and Acros II, both with sub 10 minute dev times. I’ve not seen it at 1+50 dilutions.
Thanks for the reply Can I ask what time do you use with Rodinal at 1+25? Unless it is very short then I'd have thought a rotary processor would be fine In fact thinking about it,isn't the problem with very short times is in fact the short times themselves in terms of evenness of development and if anything because you normally reduce dev times for rotary v inversion, doesn't that indicate that in terms of very short times a rotary might prove to be less problematical rather than more?
I just cannot see the link between sub 10 min times and this problem. Maybe someone can explain it but just hasn't done so yet
I am not implying that the problem you see in the negs is not there in the examples you mention but there may be another or other factors at work in those sub 10 minute times
The seemingly obvious but logically flawed way to prove it is the rotary processor on sub 10 min dev times is to revert to inversion instead and monitor the results but short of doing this by cutting each film in half and doing one half in the rotary and the other with inversion for quite a large number of occasions I have no confidence that this would prove the shorter times with the Jobo Silverbase are the problem
I am sorry as well that everything I have said appears to be negative, it's just that as I said, I cannot see why the Jobo might be the problem
What is clear is that you have a problem and I agree that a diversion as to whether the Jobo Silverbase is worth the money does nothing except distract from finding a solution
