Banding on Z9

Hi,

I've read about the risk of banding showing up in photos, but I seem to remember that this only happens at slow shutter speeds.

I'm currently editing my photos of a live concert by Swedisch guitarist Yngwie Malmsteen and noticed (what I believe to be) banding in some of my photos.

Below you see an unedited RAW photo exported from Lightroom to JPEG at a resolution of 2000 x 3000 pixels. On the photo above and around the head of the guitarist you can clearly see the banding in de red background.

Nikon Z 9 with Z 70-200mm S @ 99mm - ISO1800 - f/2.8 - 1/320s

Is there a way to prevent this from happening?

Or is there a clever way to get rid of this in post-processing?

Or is this just one of the disadvantages of a shutterless camera?

The pulse repetition frequency of the pulse width modulation of the light that's causing the problem is about 2500 Hz. This high frequency is not unusual for modern stage lighting. A slower shutter speed will help.

Some people have had good luck with dealing with this in post using a Photoshop FFT plugin.
