Kodak Technical Pan

[jappie]

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.

Many thanks,

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

I've found Rodinal 1:100 around 9'/68F with ordinary inversion agitation, EI 12, to work ok. The best with TP has been Ethol TEC.

Generally speaking, though, after years of fooling with TP I've concluded that its disadvantages outweight its advantages.

http://unblinkingeye.com/Articles/Times/Te...an/techpan.html contains recommendations from various sources on how to develop Tech Pan. I agree with John Hicks--I've lost more good shots to Tech Pan failures than to any other film.

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.

Hope this helps... Annie

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...

For 3:15 and 27,8 degree celsius?

Hi,

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:
