How learning about video improves your still photography story-telling. How good portrait lighting translates into more interesting video.
Every time I practice lighting portraits I end up porting that knowledge over into video lighting. After all, what is an interview but a nicely lit portrait that moves and has sound? By the same token, as I learn more about shooting video I learn that there's more than one angle and more than one visual point of view in a photo session. More options give me more choice. And, by being a better interviewer in the video world I've learned how to "lead" a portrait subject into a pose and expression that is more exactly what I am aiming for rather than being a session of endurance; predicated on random connections and fast reflexes.
It goes both ways. In doing both I find I am more prepared for each discipline. The more fluid I get with each practice the better my results get for each. Being able to blend the strengths of the two media is a fun exercise and a real plus. Try doing a great interview and following it quickly with a great portrait in the same set up. You'll already have the rapport on tap.....
