Multiplying the lights, that makes sense. The layers of light/shadow giving the surface a sense of the transluscence of flesh? That also makes sense. When I tried doing the three render per Anton my lighting set ups were too different and I had excessive proliferation of shadows. Maybe one studio set-up, another close to it, and a head on lighting like the flash of a camera? And I didn't think to change the colors of the lights from render to render. I can't figure out how to do the morphing, maybe a subtle motion blurr? I know the trouble with computer animation and "rotoscoping" is the absence of motion blurr in the frames. Need to try a noise bump map on one of the renders per Traveler for skin texture. Anyway, Anton sure does it beautifull. Can't wait for your tutorial!
