Hi. I have a vertical
This sounds like a problem wth the ccd (picture detection apparatus), but I saw on some web blogs that this banding can occur in low light situations, especially with a function called alo, which should be turned off to minimize this effect. I didn't see a report of this on the Fuji cameras, but it was discussed on a Canon web blog. One fellow sent his camera into the service center, and they replaced the ccd, and he still had the same problem. There was no reported "fix" for it, and one fellow said he believes it's a common problem. Another person said it occurs with his ISO set at 100, and it seems to be a inherent problem with the camera, with no apparant solution. Replacing the ccd will be expensive, and from what I've read, you might not be any better off. Some cities have digital photo clubs, and they might be able to verify this anomaly, and let you know if there's a known fix or not.
You can take the camera into a local shop to have it assessed, or contact Fuji for information about this problem, but make sure they're certain they know a fix, or you might end up spending a lot of money and not be any better off.
Good luck, and hope this helps.
