Banding in the image.

Hi,
A friend of mine was shooting a home interior and some banding showed up in the image.


I haven’t seen it in my images.
I’m guessing that it is from the refresh cycle of the interior lights.
Is there a setting I can tell them to turn on or off or adjust?

Sincerely,
William

Yes, your guess is correct.
You can try to eliminate the banding by changing the exposure time. Longer times should work better.
