I recently attended a "P.O.V. Q&A" at the Cine Gear Expo in Santa Monica on 6/24, and M. David Mullen was listed among an impressive group of DPs scheduled to speak (subject to availability).
As I studied the list, my eyes naturally perked up when I saw David's name, as I've recently read many of his posts. Other attendees included Bob Fisher, James Chressanthis, Jeff Jur, Izzy Mankofsky, George Spiro Dibie, John Simmons and Laszlo Kovacs.
But Mr. Mullen wasn't there! (along with Ellen Kuras and Bob Yeoman)... where were you M. David Mullen? :)
p.s. The panel was also promoting a great new book entitled "Reflections: 21 Cinematographers at Work" which you can find at theASC.com. It's a consolidated account of a number of lectures given by lighting/camera professionals, whose names you will certailnly recognize. This book provides in-depth explanations on how specific scenes from reputable films were shot, including lighting diagrams...etc Check it out.
