Tech Pan 120 and Rodinal

<p>I have approx 40 rolls of TP 120 (out of date) that I'd like to try. Can anyone suggest a dev time with Rodinal RO9 for pictorial contrast?</p>

Can't help with Rodinal. While it was my stand-by developer I never got it to do nice things with Tech Pan. I always

used PMK Pyro or occasionally Technidol.

 

But on that note, you're quite lucky to have 40 rolls of Tech Pan!

 

Hope the Rodinal works out for you. Seek out Ed Buffaloe and Gene Crumpler if you don't get any answers here,

though I'm sure you will.

<p>If you can't find Technidol, get Photographers' Formulary TD-3 or POTA developer. You're not going to get pictorial contrast with any Rodinal type developer, you'll be lucky to get gamma of 1.0 to 1.5.</p>

<p>Or try a low contrast document developer.</p>

<p>Tech Pan in Rodinal 1:100, ISO?ASA 64, initial agitation, continuously 15 to 20 seconds, 5 sec each 1 minute thereafter</p>

<p>68F 7min, 70F 6.5min, 72F 5.5min, 75F 5min</p>

<p>It is spectacular, wish I stil had some.</p>

<p>I like it in Diafine with a different time. 3 minutes then 1. I also presoak it when I use Diafine.</p>

<p>I have used 1-300 Rodinol for 12 minutes at ISO 40. Here is an example.</p>

<p>I normally developed it with Diafine or HC-110 according to massive development chart. May be next roll, I'll try it with Rodinal.</p>

<p>When I used TP, and I used quite a lot, I shot at EI 25 and developed for 12 mins in Xtol 1+3 with agitation 4x every full minute or in Rodinal 1+150 for ten minutes, but then then the EI should be 16 or 20. I preferred Xtol 1+3. Make sure you use enough stock solution.</p>

<p>I just looked at the MDC, and my Xtol EI is definitely more massive than the MDC (which is more or less the Kodak times). Worked well for me and for Réponses Photo where I got the times from years ago.</p>

<p>I only used Technidol and Rodinal diluted 1:300 for 13 minutes.</p>

 

<p>I have had great success with using C41 colour film developer on Tech Pan, ISO 25.<br>

Of course don't use the blix, but normal fixer and wash. Sorry I don't have the times I used with me in Shanghai.</p>
