I am planning to shoot a choreographed dance scene on a rooftop and am seeking any tips for shooting in an uncontrolled environment with a standard Canon 5D or 7D. Should i avoid harsh lighting and shoot after sunrise or before sunset? What budget lights or gels would assist? Also with dynamic shots can i still achieve nice sweeping pans left-right following the dancer without a steady cam apparatus? Any thoughts would be greatly appreciated! Thanks in advance!
