Problem with Scanning or Developmebt

[john_starke]

I’ve been developing primarily black and white film and rarely go into developing color. But I’ve noticed the last few color batches have not gone well. I originally thought it was probably in development. But I’m wondering if my problem is in the scanning.

I keep temperatures and times correct in development. Attached are some scans. Anybody have some idea if it might be in my development or in my scanning?

I scan with my digital camera, using negative lab pro. Any help would be great.

How many rolls have been developed with your curently made up chemicals; and how long since they were made up? Exhaustion of the developer might be a possibility.

It was the first rolls

Quick up date, I wonder if I’m doing something wrong with white balance either within camera or in Lightroom. Because attached is a screenshot. One on the left is from my digital camera. The one on the right is my iPhone which looks more normal.

Surely white balance wouldn't explain the weird colour difference across the frame, quite yellowish in a central band? That said, the difference with the iPhone scan is hard to explain (until seeing that I was going fo faulty light source!).

I did use a different back light for the iPhone. You think that might be it?

A problematic light source is the only explanation that makes sense to me, even more so now you say you changed it!

Makes sense to me, the iPhone image shows no banding which suggests that the problem is not with the negative but with the scanning.

Thank you! Going back to my office tonight to check
