I have looked at all the images and I see banding on the D500 images but not on the last one that Graham put up.

It is on this forum and not on any of the images as shot or any of the JPG before they were uploaded. The last D500 image of the bbey uploaded I reprocessed from the NEF just to see if there was any problem with the camera and all is good!

Have you tried reloading the problem images to see if it happens again? If they are inherent issues with the first images they should reoccur...if they don't exhibit the same issue, it would suggest an upload anomaly.

Post 197 is reloaded from the first image that showed the banding. I have also checked all the other files and all clean. This is the original JPG but full image. Click here to comment on this image.

 Click here to comment on this image. Boosting the mid tone contrast emphasises the effect and also the halo effect that Robert mentioned. I think something was different on that first nef processing. I don't know what the effect is. It clearly isn't 'digitally' regular or parallel. It looks like an atmospheric effect that for some reason the first process picked out.

Ok I think it's atmospherics that the first processing emphasised. This other image is taken from a different angle and if the mid tones are boosted, the lines are there but running at a downward angle. Turn the camera round to the left more (as in the discussed photo) and that would turn the lines more horizontally across the frame. Just don't know how/why one process highlights it and another doesn't?  Click here to comment on this image.
