strange swirly pattern on negs

[wilfbiffherb]

hi,

ive just processed some negatives and there are areas on most of the shots with strange swirly patterns similar to what you see when oil is on water. you can see it here:

any ideas what this could be and if its possible to remedy at all?

Tank or tray development?

Any other useful background information?

processed in a jobo using rollei chemicals. film is 120 size ektar 100.

Maybe insufficient bleach fix particularly if you're reusing it. It gets exhaused.

yeah i was thinking that. i may rebleach and fix again. never done that before - do you know if i can do it in the light? and for how long do you reckon i should do it??

 

[Ian Grant]

Yes you can do it again in the light and try double the normal time. Give the bleach a good shake in a partially full bottle because the oxygen in the air helps regenerate it.

In cheaper kits it's usually the bleach or bleach fix taht cuases problems.

Just rebleached and. Fixed and no change so guess it was a developerr problem,probably from using it in a rotary.

If it's not a bleach or fix problem, you may have uneven development. 3:15 is a very short time and 10 seconds of uneveness may already matter. The Tetenal kit recommends developing at 30°C with longer times in such cases, maybe you can try the same with your Rollei kit. If they don't supply times for 30° processing maybe you can infer them from looking at Tetenal's 30°C times.

yeah i guess i could try it. always wondered what the benefits of processing at a lower temp are
