Hey guys,
I was doing some filming for my portfolio yesterday and I decided to go into a Cathedral to get some footage and when I looked back the video files I was absolutely horrified to see how much "jelo" I was getting as a panned my camera. At one stage the jelo/rolling shutter affect was so bad I was convinced I had damaged my camera in some way. I've always been aware of the problems of panning with the URSA Mini Pro but I had never seen it as bad as yesterday.
However, upon examining my footage closer I realized that the main issue that was causing the jelo/tearing affect was high contrast of light and dark in the same image as a panned. For example, in the video below, in the first clip you can see immense tearing as that's where this high contrast of light comes into play whereas in the second clip of the video there is even lighting and as such there is no tearing. Also, the fact that the second clip was taken after the first gave me the assurance that I didn't damage the camera while shooting!
Could anyone please elaborate on why the high contrast of light and dark leads to shutter tearing and what precautions to take to make sure that this won't happen? It seems to me that the only sure way of knowing whether or not you're getting jelo-tearing while panning is to tilt slowly outdoors where the lighting is even.
