Panatomic X Developing Times

[braxus]

Since my other thread went off the rails, Im posting this question here. The Massive Dev. Chart does not list times for this film, so its really up to people here who still use this film recently and what you used for times.

I still have some rolls of Panatomic X in my freezer, including some 4x5 from 1969. What developing times would you suggest for Xtol straight mix, Rodinal 1:25, and HC-110 (recommend a dilution for that)? The 4x5 says its a 64 ASA film, yet on roll film its 32 ASA. I was told the sheet film was the same, so maybe shoot it at 32 ISO anyway?

"The film also seems to work really well using HC-110 dilution B for 6.5 minutes."- Kepplers Vault. Another person listed the same developer at 5.5 minutes. Kodak says 4.5 min.s

Darkroom Data Guide is 9 minutes in D-76 1:1. Stock D-76 is 5 minutes. Would Xtol be similar in time?

Rodinal is listing Panatomic X. 1 to 25, 5min. 1 to 50, 10min. at 68 degrees. Panatomic X rated at 32, developed in an invertible tank: Rodinal 1:100 for 13.5 minutes at 68 deg. F. Agitate by 10 seconds of inversion per minute.

This is why I say 9 to 10 minutes in D-76 1:1

The results at 10 minutes are ASA parameters. Every time I test this film I get full film speed, maybe a slight increase in speed.

It fixes fast too. That’s another fun fact to look forward to.

Fair warning here -- Bormental and I have noted in his "Replenished Xtol Times" thread, that he likes my favorite (current production) film at half the EI and more than twice the development. Take anything you get on 50 year old film with at least a grain or two of salt...

Panatomic-X is the exception to this rule. It has negligible fog (I test and use it) and always tested at higher than it’s rated speeds (you can refer to some old Fred Picker articles).

Even its graininess (close to TMAX-100) is comparable today with what I got 40 years ago.
