thanks, i'd have to go into the metadata in aperture to see what shutter speed/aper./iso i was shooting at which can't happen until i get back from vacation and i can get to my imac in denver, but i can tell you i was shooting with a canon 40D , one alienbees b1600 strobe, p.w. plus II's, and at the time i was just using the standard 7" reflector that comes with the a.b. strobes, but i now use the bigger 11" reflector and it definitely makes a difference! i'd be happy to post the metadata after i get back if anyone really cares that much?
