I am shooting 5x4 B/W negs.
If you get lets say a hair or piece of dust on the film when shooting, as we kno w it prints black on the print. I have tried using a 0.10mm "Rotring" pen to "pe n in" the dust on the neg so that it prints white rather than black so that I ca n retouch the final print.
Given that even though this is the finest pen available, the cure is often worse than the illness, in that the pen is still enormous compared to the dust "thick ness", esp when enlarged.
I really would be greatful for any ideas as to how you deal with this problem of a piece of dust on the neg printing black on the print; given that we aim for i t not to be there in the first place!!
