rodinal and white lines?

[atlcruiser]

Hi,
Myself and another forum member have been trying t figure out the cause of these lines.
Both frames have the faint white lines on them. Both souped on different days in rodinal 1:50 for 22min. Both frames are towards the end of the rolls. I dont know where the roll was in the JOBO tank...top or bottom.
Agitated for first 30 seconds then one gentle flip every 30 seconds after that.
Other images on the same roll turned out great...only a few have these lines and they were close to each other on the roll.
Never seen this before using d-76.

Ideas?

Looks like it may be residue from the drying, not from the developing.

Might be.

I used hypoflow for 2 minutes after wash for 2 minutes. After the hyoflow wash for 5 minutes or so then wetting agent from kodak.

I have never gotten this from any other films or developer usign the same basic process.

Hi David,

Do you get those lines with all your cameras and films?

How many frames per roll show lines?

Do they appear in similar frame numbers, or not?

I have never seen lines like those before...

Cheers,

I have had similar marks and concluded that they are either from not washing long enough or not using enough wetting agent.

I try to wash for at least 15 minutes after fix with several complete pour-outs of the water. I also increased the "just a few drops" of wetting agent I was using. Kodak recommends 1 part photo-flo for 200 parts water or 5ml photo-flo per liter of water.

Only in the rodinal. Never seen them before in any combo of film/camera.

3-4 frames will show the lines, all next to each other at the end of the roll.

I do not see them in all the rolls I soup in rodinal; maybe every other one🙂

I use soft water for the rinse then photoflow and one pas
s of a damp squigee. The film seems almost dry when hung.

The way the lines seem to go.....top to bottom...makes me thing develping tank issue as that is how the film sits in the tank. If it was a drying issue I would expect to see left to right lines as water flowed don the strip.

I wash fixer "manually" a few times for five minutes: maybe ten times changing the water completely every time. Then in new water I leave film still to let fixer come out for half an hour... Then wash and in new water I pour a few drops of wetting, mix and leave film on it for two minutes, wash a few times again for five minutes, and leave film still another half an hour in new water... Finally I wash with distilled water for two minutes and hang to dry.

Hope this helps,

Cheers,

Juan

i guess the big question does rodinal need more washing than other developers?

The rolls i have done in rodinal with the exact same washing process have also come out perfect.....perfect minus my poor exposures 🙂

You could try soaking and drying the negs again.

Seems unlikely it would be the Rodinal causing a residue problem since there are several other liquids coming into to contact with the negative after the Rodinal, i.e fix, hypo, water and photo-flo.

 

[Juan Valdenebro]

Not related to Rodinal... And it doesn't need more washing than other developers... In fact is fixer what we wash...

If all lines are by the end of the rolls, there's where the answer is hiding... Light or chemical contamination are involved...

I am almost 100% sure it is not light.

Chemical I can believe but why only with the use of rodinal? Other aspects of the process stayed the same.
What about agitation?

If the "lined" sections are on the very end of the roll that would be the section on the outside of the reel in the JOBO tank.

 

[Juan Valdenebro]

But the lines are not parallel and don't show the tank's internal streams...

Do you develop more than one film in the tank?

Cheers,

Juan

 

[atlcruiser]

Yep...either 2 or 5 rolls per tank

Do the lines go across the film or along the length, ie if 35mm sprocket to sprocket.
Just wondered if there could be any liquid residue left in the reel prior to loading that dribbled over the film, sort of selective pre-wetting.
