I had this happen once with E100VS. There was nothing wrong with the
exposure. It was disappointing, because I liked the shot otherwise.
The scene was a blue door against a brown adobe (mud brick) wall.

Hi,
ISO was 200. Shot was underexposed by a couple of stops.
That'll do it. You can't do that with digital.

Underexposing is pretty much the same thing as using a higher ISO and
amplifying the signal from the sensor.

G'day Shel
The only times I see this are either on underexposed shots, where I
had to do major PP to get a usable image, or when shooting at high
ISO. At High ISO, generally the first 2 or 3 shots taken in quick
succession are fine but after that it becomes noticeable. An example
can be found here
I always use somewhat tighter, if not necessarily optimally sized,
hoods.
But I don't think that this is the cause of the problem. The cause
seems to be a combination of underexposure and effects of fluctuating
power. I've never seen this kind of banding on any of my cameras
without under
It's a "digital" moiré pattern and usually an artifact of digital processing
within the camera. How was the photo saved? Raw?, jpg? how much compression,
if any?

There are several causes.
Here are three:
#1. The wrong film.
#2. Exhausted developer.
#3. Exhausted fixer.
#4. Low ink levels/dirty heads.
... and most important of all ...
#5. Unrealistic expectations of the medium.

Fair enough, are you using tighter hoods on your lenses than you would for 35mm
full frame use?
Why I ask is that I have a yet unproved theory that the sort of banding you saw

There you have it. Artifacts like these will sometimes appear in the shadow
area of underexposed shots. You can sometimes get lucky with two stops under
and end up with a nice image, but it's always a stretch. Of course, two stops
under with color neg film returns nothing but grainy mush, so I g
