lighting portraits inside church.

[turbo212003]

Background: Shooting 4th wedding. Need to lighting for portraits.
My last wedding, they didn't want posed pictures so I didn't do any.
My question is: will two Calumet Genesis' 200's work for portraits with umbrella's? I haven't shot any portraits inside a church. From my understanding, the church is small. I was thinking one on the left and right hand side. Would this lighting be too flat?


I will be using a 30D connected to PC sync , so cord from one strobe then using the optical photo cell on the other.

Any input would be nice..

200 ws at iso100 is like 800ws at iso400, so if you can deal with higher iso, 800wsx2 is plenty.

Flat lighting could be caused by equal amount of light from the main and fill, set them at different ratio should take care of that.
