I keep going back and forth between the AlienBees B400 and the B800. I will be doing primarily portrait work to begin with, so the B400 seems like a good choice so that I can use a larger aperature. However, if I'm later doing more fashion oriented photos, or even outdoor photos, I'm afraid that the B400 will not emit enough light. I know that I can always diffuse the light from a B800 if it is too much, so it seems that the B800 really could be used in any event.
Is there anyone out there who knows... is there any situation that the B400 won't work well in so that I may need to consider the higher powered strobe? I'm trying to think ahead, and if my strobes can all be the same power, then it will make my life easier.
