I was recently flying in a small aircraft, and took a picture while on approach, with the propeller going relatively slowly. Regretfully, I had forgotten that my camera was still in electronic shutter mode, so the propeller got all bendy and wobbly in the picture.

In addition, however, there is a small sawtooth effect on the propeller that I can’t make sense of. It seems as if there was some interlacing going on, with different image rows skipping back and forth in time.
Is this how modern image sensors are supposed to behave? I hope that there are a few technical people around here who can shed light on what is going on there!
