Thank you all for the great advice!
I'll be scouting the location again at different times of the day. The difference probably here in the Philippines is that the sun stays at a 90 degree angle, like a noon sun, longer than in the States. And it comes in earlier, so by the time we'd have set up we have that harsh midday sun already. It seems that it rises fast, stays there, then sets fast as well.
I also got a 2500w HMI for the mid-shots and closeups, and a bunch of reflectors.
