Here you will find a collection of microscopic shots for most of the strings and string sets that I test and have studied. I find this as a good reference, particularly in comparing wrappings and surfaces, of various material strings. This list includes pictures of silk strings, composite strings, metal-nylon strings, my own experimental strings, and other interesting photos such as textile fibers, string cores, string wrappings, and string layers. I am using a simple and cheap microscope, with a x40 magnification, taken through the eyepiece with my smartphone with a x1.6 zoom.
