I am new to shooting a Hasselblad H4D-50, and need to light 6-8 folks. I'm going back and forth on how much strobe power I want, having used the Bowens 400w/s kit and a pair of Profoto AcuteB 600w/s. Based off my experience so far I feel like I need to go to a higher w/s power level, but how high? I am considering the Einstein's (yes, I'm in the USA) but fear the 640w/s would be too limiting.
As for modifiers, I would be getting a beauty dish, a large octobox, and a couple of umbrellas. My fear is that I'll be running at max power when shooting more than a few people, and being limited in what modifiers I can use. Toss in that I want to be mobile, so what ever power level I go with, I need the ability to go to battery as well. Am I over thinking this?
Thanks in advance.
