A JVC Everio GZ-MS110BU digital camcorder took the videos 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 videos clearly show the flashing iridescence of many of the knobs, from one overhead light and one side light. For some, only images are provided. A few are added for reference, with no image or video.
Some of the videos have failed to be embedded in this page. If they aren’t working try the Tulsa Sound Guitars YouTube Channel., or try copying the YouTube URL into your browser.
