Hi, I would ask if somebody has experience with the combination of Kodak Technical Pan-film (120 mm) and Agfa Rodinal developer and will share this information? To use in portraiture and landscape photography.
I have not used Rodinol. I have used Tech Pan a lot - in both 35mm and in 4x5. I have used Technidol, TD3 from photoformulary and D23-split. Technidol was OK - maybe N+1 or so. TD3 was the best. D23- split was maybe N+2 and surprizingly good. I can give you the formula for D23-Split if you want - Frank
Barnbaum uses TechPan for N+ situations. When he processes it he agitates VERY VIGOROUSLY! Actually slams the hangers down into the tanks. Not sure what this does but seems to work for him. I think he uses HC110 for the developer but could be mistaken. After the course I am taking from him in June I will be able to tell you for sure.

Just as a side note Bruce uses TriX for normal development, HP5 for N- situations (he finds HP5 to be off to low a contrast for normal development) and as said the TechPan for N+. His main developer is HC110 in various dilutions. He has a bunch of Grafmatics loaded up say two for each type of film and just throws in the one needed depending on whether he figures he's going to have to do N- etc. development.
In his writings Barnbaum states that he uses a Two Solution Compensating version of HC110 for Tech Pan. Which I will paraphrase here....
Solution A. 1 stock:7.5H2O Solution B. 1 stock/45H2O
The method is:
Solution A... Agitate 50 seconds/no agitation 50 seconds...transfer to Solution B
Solution B... Agitate 20 seconds/no agitation 1 minute
(Total so far 3 minutes)...revert now to usual agitation of 15 seconds at the start of each minute...to a Total of 10 minutes.....Fix as usual.
His concept is that the initial 'jump' in Solution A retains the low zones that are lost with full compensation development. Also increasing agitation in solution A will increase contrast.
I have used this method with some success rating at ASA 25. One final point only develop a few sheets or 1 roll at a time and use a 90oz of Solution B so there is no exhaustion of the highly dilute developer... use B as a one shot.
Before I discovered TD3, I tried tray development with D76 1:1 and a tray of water. It was 2 minitues in developer with agitation, 2 minutes in water with no agitation, 2 minutes in developer with agitaion, 2 minutes in water and no agitation and lastly 2 minutes in developer with agitaion and 2 minutes in water without agitation. This did produce good results from Techpan. - If you like tray processing.......
Try tech pan in C-41 without the bleach step. Really better tonal qualities than Technidol. Weird look, but it seemed to work better for me than using any B&W developer...

I have used technidol and rodinal 1+100 with TP.
In rodinal I used semistand, 1h: first minute constant agitation and 3 agitation on 30 min. Here are some scans of results in rodinal:
