Is that on the examples, what Trius talked about two weeks ago - uneven development on pictures with many highlights (snow)? What can I do? This is tri-x rated 400, developed directly after P. Lynn Miller instructions on page 2 of this thread (prewash, 1 minute slow inv., 3 pushes to dislodge bubbles, 59 minutes standing), Jobo 5- reel tank, first and last reels empty, 3 reels with films centered. 10,5 ml of Rodinal (3,5 to roll), 1250 ml distilled water. What can I do? Turn tank upside down in middle?Do 3-4 inversions after 30 minutes? Or could it be better in smaller tank?
Dark motives also have halo, which can be seen when darkened. Pictures are nearly directly from scanner, only bit of contrast added to make problem more visible
Thanks everybody for any help

I have been shooting and processing my own film for a while now. I have processed hundreds of rolls of TRI-X. My main formula was/is D76 1:1 for TRI-X and Neopan 1600 and Rodinal 1:50 for TRI-X, Neopan 400@ Neopan 1600.
I always managed to obtain consistant results with these dilutions with both developers. And I mean always.
Then I read this thread about stand and Rodinal at 1:100. I decided to mix things up and then started to run into problems with exactly the same effect that your photos are displaying. I also got air bubbles that I have never encountered before. I always bang the tank very hard, but at the end of the day I'm not sold on stand for a number of reasons:
a) Convenience - people argue that it is more convenient, as you tip in the developer and then crack a beer come back in an hour. Well, that is something that you have to remember in an hour. I prefer to stay focused for the 11 minutes at 1:50 and do the job guaranteed.
b) Temperature - well, where I am now in Malaysia the temperature has been outrageous, so even with a water bath the temp is rising too much. I prefer to keep my Rodinal at 19/20C so this is more difficult with an hour development. Coming back to that theme of convenience or lack of it.
c) Highlights - I don't like what it sometimes does to highlights. I shoot under contrasty conditions and this banding effect looks strange and draws attention away from the subject.
d) Air bubbles - I have had these from time to time with stand.
So, I have come to the conclusion from a lesson well learned, that stand is not for me personally. I want guaranteed results for important subjects and there are just too many variables.
SO
My favorite combination is TRi-X at EI:400 for 11 minutes at 19C.
Or TRI-X at EI:200 for 9 1/2 minutes.
Neopan 1600 at EI: 800 at 11 minutes.
I agitate for the first 30 seconds, then 1 slow agitation at the start of every minute after that. I rotate as I invert and have found it unnecessary to agitate twice a minute if you maintain good form, hence preventing uneven development.
BUT
as this thread is about 1:100, I will say that I DO like this combination occassionally, BUT not with stand development. Instead, I develop TRI-X for 20 minutes at EI: 400 with 1 agitation per minute with this dilution. The results are good for high contrast lighting with large stop differences between the shadows and highlights.
In conclusion, if you are having strange unwanted side effects with stand, then just move onto regular agitation cycles, because in my opinion it is overrated and not worth the potential trouble and time.
