Tech Pan in 2019??

hi all
How does one develop tech pan nowadays (lacking technidol)?

I got rodinal and diafine in house, and i have access to xtol and amaloco film developers.
I would like "normal" contrast level.

Any experience? And what EI with the developer you would suggest?

You could start here:

Photographers’ Formulary makes their version of Technidol called TD-3.

I would shoot at EI 25 and either use TD-3 or a fairly diluted standard developer.
You might also have luck with stand developing as it tends to keep the contrast in check.

You’ll Also find a fair amount of data on the massive dev chart listed under “discontinued films” as well as a couple of time/EI combinations on filmdev.org.

Here is the way I do it:

John Carter
Kodak Technical Pan Rodinal
I was given three rolls of 35mm Kodak Technical Pan (expired 2002). I hunted around for a development scheme and finally settled on this. Mostly because I had Rodinal. I'm only posting in case some of you still have some in the fridge.



16 EI



Rodinal 1+150 for thirteen minutes



Agitate with 30 seconds initial inversions, then 3 inversions at 10 minutes,7 minutes,4 minutes, and 1minute counting down. (every 3 minutes)



Regular stop, fix and hypo.



I used 5ml of Rodinal in 750ml of H2O. That gives less than the recommended 10ml of Rodinal but the negatives really look great (full tone scale).



I had to figure out a curve profile as I felt (and still do) that the midtones were not right. Technical Pan is also a dust magnet; lots of healing tool. Even with Rodinal there is virtually no grain.



EDIT:



With this last roll I used a Yellow filter which made life easy to post process.

There are more so to see click on the photo and look around. https://www.flickr.com/search/?user_...cal&view_all=1

These were taken in the last two years.
