I've been working on even development of 8x10 negatives and noticed that every negative I scan has distinct vertical bands. After a few rounds of this I noticed it was the same bands on every negative. From a few google searches, I understand that this isn't uncommon and has to do with the way the light source for transparency scanning is made (an array of LEDs). Here's an example of a scan of an unexposed and fixed-out piece of x-ray film. It is perfectly clear, blue tinted:
The vertical banding is not on the negative.
I have never noticed at 4x5 and below.
My question is whether I have a bad scanner or this is just characteristic of V800s at 8x10.
Thanks,
Sam
