Slightly off topic.
This brought flashbacks of my D70 and taking photo's of candles and bright lights.
But the real issue with my D70 wasn't the banding, it was the back-focus that I never had taken care of. In retrospect I didn't send it in for repair/adjustment because "I didn't want to miss any photos", these are the same photos that are still out of focus to this day...
Lesson learned.
Hopefully the banding doesn't occur often!
