(New) Problem in Developing Ilford PanF+ in Rodinal

[aa]

I just developed the last 2 rolls of a 12 roll project shooting

Ilford PanF+ at ASA 32 and developing in 1:100 Rodinal, and

encountered a fogging and "splotches" problem on just these last two

rolls.

 

See here for an example:

Notes:

The temp is always 20-22C and I adjust the time accordingly. (from

13.5 minutes for 20C)

 

I have used the same stop and fix (Kodak) throughout...I wouldn't

think this was the problem since the last two rolls developed were

fine,although I probably don't change these solutions enough.

 

I do not re-use the Rodinal.

 

The ambient temperature of my darkroom(bathroom) has dropped a few

C's, so maybe the Rodinal precipitated (I thought Rodinal was always

this way though).

 

I seem to remember usually shaking the 125mL Rodinal bottle

vigourously before use, and don't recall doing that when the problem

occurred.

 

The film is loaded in complete darkness, the stop and fix are added

in almost darkness.

 

I use a plastic 2 roll Patterson developer.

 

Both rolls were at below freezing levels in strong wind and right

near the ocean.

 

I can't think of anything and would hope that someone with a lot of

experience can look at film and know what happened.

 

Thank you,

Try refixing the film with fresh fixer.

I agree with Michael. It looks like your fixer was exhausted. I use Ilford Rapid Fix one-shot

for 4-5 minutes, giving four inversions every 30 seconds.

If the temperature during shooting was at or below freezing there's a chance that static electricity could have produced those smaller marks when advancing or rewinding the film. Wind on a cold day could make matters worse. So could the use of a motor drive or rapidly winding the film.

Try refixing but I don't think thats your problem.It looks like bad agitation or air bubbles in the developer.The full frame photo looks underdeveloped in the middle compared the the top & bottom.

[chris_waller]

Like Melvin, I would suggest that air-bubbles on the film are the problem. Try a pre-soak or more vigorous tapping of the tank when the developer is poured in to dislodge the bubbles.

My vote is static electricity also. The dots are uniform and of positive density, like static would generate. I've seen it before on film left in the camera for some time.

 

Was this roll film (120) or 35mm?

The refixers win the prize!

 

I refixed for 40 minutes with my (obviously) spent developer. This cleared up the problems on the images (but the film is still slightly fogged overall). I'm awaiting a B&H order with some new Ilford one-shot fixer (thanks for that heads up).

 

I think the static electricity was a good suggestion, but kind of hard to tell from the one frame I posted. In photo class, the instructor showed us some examples of static electricity problems and it looked a bit different. (Plus I am careful now to rewind film slowly and while it was cold, the humidity is probably pretty high right on the ocean?)

 

Thanks again everyone, this board saved the day. (I printed one of the pictures tonight and it is my most favorite picture in quite some time!)
