Hi, I was given a sample of some photographs taken of the propeller of an airplane made with, I believe, a phone camera. There is an obvious anomaly present. Although I suspect the reason I am not really sure (really I do not know!) how this came about. If you can shed some light on the effect for me it would be much appreciated. See the images here: http://people.rit.edu/andpph/a-misc/phonecamera-prop-effect-1.jpg Thank you for taking the time to give me a hand! cheers, andy
