Money shot

From the Wikipedia entry for Davidson, Didier:

Didier Davidson was one of the early practitioners of the use of infrared phtographic techniques in adult films.

Here we see a single frame screen grab from one of the 'money shot' montages which brought him great fame and a small fortune in the mid 1970s.

-Thank you, U.S. Geological Survey
