I need to photograph an instructor in the gym for a gallery of some lifting exercises (will be used in an application and on the web).
I want to look pretty dramatic and powerful, though instructive (that's their purpose).
The photography will be in an open gym (so the lighting is not powerful or any good) - What lighting should I use? How should I approach this?
I'm using Sony NEX-5N with 50mm lens.
Thanks!
