Plastic Knobs

A JVC Everio GZ-MS110BU digital camcorder took the video(s) posted here, of knobs rotating on a neutral-gray DIY turntable.  Unfortunately, even the “Ultra Fine” setting produced rather fuzzy recordings, and even falling back and using a telephoto lens setting improved the depth of field only a little.  Nevertheless, the video(s) clearly show the flashing iridescence of one of the knobs, from one overhead light and one side light.  For some, only images are provided.
