Another scan question....

Scanning some B&W negatives from my Yashica-D today... In several, I notice some dark-light pattern in the sky: vertical 'beams'. They seem to originate from the scanning? What is the problem, how can I avoid them? I am sure they weren't there in real life....

I'd guess it's due to the agitation pattern when the film was developed. How's your process for development?

Well.... I look out to check the weather, get my coat and shoes, and an umbrella if necessary, grab the film and bring it to the drug store at the corner, about 2 3 minutes walk from here in our village....

Without kidding.... it's not in all the shots in the same roll, and I don't see it in the negatives....

Yeah, it looks like uneven development. But it looks straight enough to look like scanner banding too. Was there a large gap of clear glass before the start of the negative when scanning?

Ditto on developing problem. Most likely you will not see it in the negs. The scans ad the contrast and context to make it visible. I would suspect bromide streaks, possibly spent or contaminate fix or developer.

Rotate those two negatives 90 or even 180 in the scanner if you can and scan again. If the streaks are identical to the original, we have a clue.

the lonely cloud looks very Dutch to me (but I may be biased)
