Last week I had an extremely unpleasant experience.
I developed an Efke R50 (emulsion number 110541).
Apart from the fact that the film was a real struggle to load, once dry it showed a curl that was strikingly reminiscent of a corkscrew. The film simply won’t lie flat at all – not even in the negative sleeve!
As this is the first R50 this has happened to me with (I’ve heard similar stories from others), I just wanted to ask here.
Is the R50 now living up to its name as a ‘ROLL’ film? <_< :blink: :)

Uwe,
Have you finished editing the film yet?
The issue with the curl has already been discussed previously.
Nothing has actually been changed in the films themselves, but if the humidity changes, the effect becomes more or less pronounced.
You won’t get the Efke quite as flat as a Kodak or Ilford, but you should at least be able to get it as flat as an Agfa if you follow the rules below:
1) Use film holders
2) Allow to dry slowly in a room with high humidity. Ideally in a shower cubicle with hot water in the shower tray.
3) Do not edit/enlarge in rooms with central heating and no humidification.
Ferdinand: Curl depends on the base film and is independent of whether the film is old, new, domestic or export.
The NC (no-curling) emulsion is applied during the production of the base film.
When selecting the goods, we can only influence parameters that are production-related.
Best regards,
