This site is partly about sharing frustrations in learning film photography. A difficulty I am having at the moment is the appearance of tide-marks on my negatives after processing with Tetenal C-41 kit using a Jobo.
The tide marks are very evident in the photograph below. Shame, as I quite like the picture. I can clean the negative, but of course it’s better to avoid the problem in the first place.
‘Googling’ the problem gives a range of recommendations: Use filtered water; use distilled water; reduce the concentration of the stabiliser; omit the stabiliser altogether; add photo-flo to the stabiliser and so on….
As I like to use Ilford XP2 film, I need to find an answer. So, I will report back. Grrr!
I think I have resolved this. I added a very small amount of photo-flo to the STAB bath, then I washed the finally processed film in a water bath with a little photo-flo. Seems to have worked and hopefully I have not annulled the effect of the stabiliser.
