I am using a Canon 5DsR in conjunction with studio flashes and an automated turntable by Ortery to take 360 degree photos of objects. I know that if you have your shutter speed set too high you will get a black bar at the bottom of the image due to the shutter. We shoot hundreds of images, usually in sets of 36 images per rotation. Once in about every 2-300 shots, I get the banding issue. It is VERY rare, but when it happens (because of the way the software works) I have to start that rotation again. Unlike the typical "you have the shutter speed set too high" issue, this seems to be a random hardware failure issue. I am not sure if it the camera, the wireless, the strobes, or the software, but would like to get your thoughts since it is so inconsistent. Here are two examples of it happening. Thanks in advance for your help.
