Hi guys,
i think i've really come to a point where i need some serious help. I get some vertical streaks on many of my scans, especially in denser areas of the negative just like sky etc.
I tried several modifications to my workflow, but until now i can't figure out whats happening. So i'll just describe my workflow and what i tried, maybe someone of you has an idea.
First, this is what I'm complaining about:
It's actually a scan of the whole 35mm negative (landscape orientation), i just cropped out the person on the right, thus giving it a 1:1 aspect ratio. Those bands or slightly darker areas running from the top all the way down to the bottom of the negative are also to be found in many of my images here in the RFF-Gallery. They are very prominent especially in thumbnail view.
The phenomenon first occured some 2 years ago when i used TriX with Rodinal. After that I changed developers (first Atomal, now XTol 1:1). I tried to reduce my agitation which had been very strong (now 30Sek slow continous inversion followed by 2 gentle inversions / 5-6 Sek every 30Sek). I even tried stand development, but scans still show this pattern.
At some point i thought i had tracked it down to bad fixer, as the negatives had not completely cleared and showed a similar pattern of remaining emulsion. But after i fixed the same film with new fixer (negatives now look completely clear), the banding remains to be seen on the scans. For the time being i use my fixer as one-shot, to avoid a similar experience.
I thought about chemical contamination and cleaned my reels and canisters to no avail.
I used Silverfast and changed back to the original scanner software on two different computers, but i still get the same dreaded banding.
When i look at the negatives on a light table, they look completely OK to me. No density differences or vertical lining pattern in the sky. So I thought it was a scanning issue, but when i scanned some C41-film, which had been processed in a professional lab, i had no problems in the sky areas of the image.
Needless to say i'm a bit frustrated. More than that, i don't know what to try next. More agitation? Even less? Try another scanner? Shoot digital in the first place?
Thanks for reading this lenthy post. Feel free to ask me if i've left something out. Every contribution ist greatly apreciated, so please give me a hint if you think you know whats going on.
