I was making some enlarged negs from 120 B&W positives on Ortho Lith film yesterday and kept getting streaking along the dark areas of the film. My procedure was to pre-wash the film for 1 minute and tray develop in Tanol staining developer for about 3 minutes with continuous agitation.
As my agitation was mainly in one direction, I tried again by agitating in the other direction. The results were a lot better but on closer inspection I could still see slight streaking as per the new direction of agitation.
So is it simply a matter of evenly agitating in both directions or is there any other reason for this problem?
