Photographing takes place at the moment when pulsed light sources are triggered synchronously with the model's move-ment. Under these conditions, shadow visualization schemes are functional, which represent an upgraded method of a luminous point using a protective lens, a combined method that in-cludes registration in passing light using a camera with an electron-optical shutter, and a shadow background method. Typical registration patterns are given.
