The Klaus Schreiber Method
One of the most important and interesting techniques for making Video ITC recordings was pioneered by Klaus Schreiber in the 1980s. Schreiber's method involves recording from a video camera that is pointed at a TV or video monitor which itself displays the output from the video camera. This sets up a feedback loop between the camera and TV which, when the camera is correctly adjusted for zoom and focus, results in strange visual displays.
The effect generally sought is one where swirling clouds appear. Best results are obtained when the camera is focussed just beyond the TV screen (i.e., the image is slightly out of focus). Somewhat different results are obtained depending on the distance between the camera and the screen (which may be from a few inches to a few feet).
