Looking at the alienbees and gotta question. I have a canon xsi with 1 430ex. I will be doing real estate photography and wondered if I could get good results with 1 800w alienbee, or 2 400w alienbee, or exchange my 430 ex and buy 1 580 ex II?
*If you know how use your equipment. Bigger/more equipment isn't the secret, knowing how to use it is! Personally, for this sort of work, I would pick up a few old Sunpak 500s or Vivitar 285s for their portabiltiy.
