Pan f + at 400

[Trius]

Allan: Thanks for the clarification. I've only used DDX once ... for Pan F+, coincidentally, but at "normal" EI. I found an EI of 32-40 to look the best, but 50 wa was not bad at all.

Bill: Good plan.

Trius,
You got 32-40 out of Pan F in DDX? Intriguing. I haven't tried Pan F much yet in anything other than Rodinal. ID-11 1+3 and Perceptol 1+3 are my next test develpers.

Pan-F at 50 in Diafine is something I like, so perhaps I shouldn't be chiming in here...but that's going to be one HELL of a push. It's most likely going to look crappy in whatever you use, but at least it'll be a picture. If all photographs were perfect the world would be boring.

Allan: The roll was developed but not contact-printed or scan, so my evaluation was very cursory by examining negs with a loupe. EI 25 was too heavy, but probably useable. 50 seemed useable, but perhaps thin for optical printing. Man, I need a darkroom. Or a good scanner.

Like Stephanie, I run Pan F at EI 50 in Diafine. But I have wondered about the effect of souping a film (not specifically Pan F) through Bath A then Bath B as usual, then wash thoroughly, and repeat A & B, then rinse, fix, etc. As a super compensating developer, it's possible it might then work some more on the low-density (shadow) areas increasing effective film speed at least to some degree without totally blocking up the highlights. But I'd think even this would not avoid very thin Pan-F @400 negs...

Diafine is a compensating developer, but it's more accurate to describe it as a 2 bath developer. You get the first when you have the second, but saying Diafine is compensating isn't the same as saying Rodinal or FX-2 is. They're just different.

Also, note that Diafine yields specific speed increases, in varying amounts, for different emulsions. For instance, you get 1250 out of TXT, but not out of HP5, another traditional emulsion 400 speed film. So the results of Pan F at 50 in Diafine does not necessarily mean much in terms of what will happen when it's pushed even further in entirely different developers..

But yeah, that'll look pretty crazy no matter the developer 🙂
