Hello all,
I have a problem that I haven't been able to solve on my own, so I'm turning to you for help.
Important facts:
- Film: Ilford Delta 100 4x5
- Tray development: soak for 2 minutes in water, EcoPro dev, water stop bath, TF-4 rapid fixer
- When I place the negatives in the initial soak tray, I place each one individually and submerge it fully before placing the next negative in the soak tray so they do not stick together.
In the attached image, I have two more-or-less identical negatives. They were both processed in the same manner but at different times. I generally develop 3 or 4 negatives at a time in trays by carefully pulling the bottom-most negative out and laying it gently on top of the stack. My dev times are usually 7:30 to 9:00 minutes, and I achieve most of my agitation through the shuffling of the negatives. (That is, I don't rock the trays very often while developing.)
As you can see, the negative on the right has a few odd streaks that are noticeable in the sky, while the negative on the left doesn't appear to have any streaks. Looking through my catalog of negatives, I find these streaks are somewhat common. I have also attached a crop of the area in question. Further, I have provided direct links to a Flickr page since I can't figure out how to show these images in full size in this forum.

I have no formal darkroom training, so when things like this come up, it raises a few questions:
- Is this normal for film, and I just have to deal with it?
- Is there something that I need to correct in my development procedure?
Thank you,
John
