It is difficult to know to what extent I carry on Helmut Ruhemann's inpainting techniques faithfully, or to what extent I have devised methods which suit me and use newly developed materials. However, my thinking is still closely based on Ruhemann's teaching and philosophy, and I hope and am persuaded that nothing I do would meet with his disapproval. Of course new materials often simplify methods, but they do not really affect the fundamental principles.
