dynamic range is kind of a constant - I think you're speaking more of scene luminance ratio. the most helpful thing is simply to use grads from the side top and bottom. that's always been my recipe. a butterfly is nice to float in over an actor. or whatever you have a flexfill on a boom pole. I used to use reflectors on a yoke and there amazingly effective if you can move freely for short scenes. There only two things you can do - remove highlights (grads) or pump up the fill (adding light) .
I'm not sure but camera tweaks may buy you a stop or two. the scene luminance is 100:1 which you have to fit into 12:1 or so.
it's the same old game.
Graduated ND filters are the big one for leveling out exposure with a bright sky, throwing more light on your subject and exposing accordingly is the other biggie.
