First thing is to make sure that the flash heads are not too far from the subjects, as aperture x distance = GN, you can see that the further the flash units are from the subject, the more the aperture must be opened to account for the reduction in light. Also, as the light falls off dramatically with distance you'll have to position your subjects so an even amount of light falls on all of them - people further away will be illuminated less than the people at the front. One way to overcome a lot of these problems is to bounce the light from the roof, but it depends on the shape of the room, the amount of light the roof absorbs, the height of the ceiling and the size of the room.. I suspect you've taken these things into account (I'm assuming large room rather than small people) so I guess you DO need a lot of light. this sounds like a difficult lighting issue, maybe someone with more experience of interior lighting could jump in here with a few suggestions? karl (6 metz-60's ;-)
