I hate to say it, but I still see what suspiciously looks like light fog.

Tomorrow or after tomorrow I probably show you a clean one! I still get several rolls.

Actually, tonight I loaded it on a reel which is a little bit wet.
I don't know if you have any experience when you scratch the surface with your finger when load the film on the reel before development.

The result is the same. The trace turns to be dark on negative.
I realise that if I rotate the tank very violently, it's the same effect and much more because the wave is the physic scratch and the chemistry leaves the double effect.
Even water is soft, it's still there. So it's the same thing as you scratch the surface of the film with your finger.

Because of water, it looks like fog.

Agitation, more precisely local streams, can only have effect on already exposed emulsion.

You are saying that violent rotation, as scratches, due to the water will make friktion marks, which then show as density.

No way.


Actually I meanwhile lost understanding what you are doing.
The majority here regards your artefacts as caused by a light leak. You hower are going on processing, showing that things get better.

Maybe it is violent agitation, with two litres of fluid, that is causing a light leak in the tank.
