I took quite a lot of pictures in a stage recently. I believe it was flickering effect of LCD/LED lights and my shutter speed, stripe shadow bands were seen on many pictures. (A sample is attached for illustration) (Due to taking photos in a theatre, I had to keep on using silent electronic shutter mode which did not work together with anti flicker feature of my camera!)
Due to the quantity of pictures involved, I want to receive advice of any filters, actioon steps, or other hints to fix thesse shadow bands in a batch. Many thanks!
