I keep a Zorki in the truck for grab shots and such and finished a roll yesterday.
I always have T max 400 in it, but when I opened it I had a roll of Pan f +. Any ideas as to how long to process it. I use T max developer but the fastest speed listed in the Massive chart is 125- 7 min @ 20C. They list 4 min. for 50. Is there hope or utter dispare?

I always keep (part of) an Avery label on baseplate and top plate, and try hard to pencil on the film and date, top and bottom.

Duplicating the info on a PDA - against camera serial number

Frequently fails of course, and no help to you.

You probably need to two bath it is in something really strong, some one will help.

Pan F doesn't really like to be pushed. Off the top of my head, I'd suggest stock Microphen for somewhere between 15 and 20 minutes. But the results are likely to be contrasty.

Thanks Kully, I like the ideas there and will see if anyone around here has any microphine. The most interesting thing about that link was the mood of it, not what I have come to expect here on RFF.
Thanks for the help

Bad luck with your film accident. . . It could be interesting though !

If you can find any times that look realistic, maybe you could clip-test the first foot or so of film, to get an idea of any adjustments needed ? You could then immediately use the same chemicals for your adjusted time of course (assuming you have a dry reel for the main bit of the film).

Good luck . . . and keep us posted.
 
if your timing is 10mins at 50, then do it for about 25 minutes. I've done it once. I used warm water and doubled my development time. The results were a really dense base, and slightly underexposed. Results were ok-ish

To be honest I think there is no hope. Pan F does not make 50 without a serious fight so 4 stops below its comfort speed of 25? Forget it! I would throw it out and not waste the time unless you have some shots you heavily bracketed with over exposure and which are important. Even rated at 100 you would need to work very hard to get decent negs with a semblence of shadow detail. If you do pull it off let us know!!!!

Well, another nice thing about Ilford's phenidone developers - Microphen and DDX - are that they don't build base fog by much. They also are extrmeely forgiving of overdevelopment. It's not really compensation - I'm not sure what it is. But I knjow that I've shot TXT in my Canonet at "something more than 800" and just thrown it in Microphen for 25 minutes - well beyond the 16 I use for 1600 - and it has come out very acceptably. So you can be pretty aggressive with your times with Microphen and you'll be okay.

The alternative would be a compensating developer with lower agitation and extended times. HC-110 would work, but you'll be in the 30-50 minute range. And I have no clue where in that range.

Pan F negs will not respond like TriX to pushing. It builds contrast very fast and one to two stops puch from box speed with TriX is nothing like 3 stops on Pan F. I will be astounded if this can be pulled off as even pushable films dont really deliver the full shadow speed of theirr 'pushed speed'. Pan F is probably the biggest pig out there when it comes to speed....I suspect if dev time is upped too much the silver will be so thick in the high;lights that you could make a bracelet out of it.
 
Allan: Are you sure about the DDX not building base fog? I have consistently read that is the one knock against DDX, and confirmed by a photographer whom I respect who processes/prints commercially.

If the Pan F+ were mine to process, I would use HC-110 Dilution B, but I'd have to think about the time. I agree there's not much hope for the results, except with respect to contrast. Water bath development might be the way to go.
 
Trius,
I should've qualified more - my experience is with Microphen. I was thinking that almost everything about Microphen applies to DDX, but I should've said that I wasn't sure about DDX in particular.

I also never meant to suggest that Pan F can push like TXT. But the question isn't whether it'll push well. The question is what to do. My suggestion is to take a phenidone-based speed-increasing developer, like Microphen, and give it a shot. Compensation would be another way, but that is a lot harder to estimate - you need to test. And who would spend a lot of testing of Pan F at 400?

Trius, I found some HC 110 this weekend so my plan is to roll a short roll or two of panf and expose at 25-50-100-200-400. Then develop at normal and 2x time.
I have't used HC 110 for 30 years but I remember it being easy to use mixing for one shot.
None of the pictures on the underexposed roll are priceless but I now want to see what can be done. I'll try to post the results.

Did you see some of the responses to that guy's innocent query on the Photo.snot link? Man, what a bunch of jerks. Thank God for RFF.....
 
Thanks for the link for push processing Mark, I somehow have missed it. I have the table printed out for Tmax developer and keep it in the darkroom. 4.5x with hc110 would be 18 min., the same time that the Ilford tec. advised on the Photo.snot (glad I'm here not there) link. I was suprised that Microphen and Tmax are both compensating perhaps I'll try Tmax 1-9 on a test roll as well.
