Advice wanted:
This large church is going to be dark inside at 3:30, one, because most of the overhead lights will be off and there's only one entry through stained glass. I tested with 580ex II on flash bracket using my 70-200 2.8 IS L., with a Fong cloud LS aimed straight up and the FES at +3. Bare in mind I'm standing on the other side of the church. Even w/o flash at ISO 3200/f2.8 it's dark!
For those standing up front during the ceremony, mainly along the sides, like the singers are getting a slight shadow casted off the subjects. Is there any way to avoid this at all....I'd rather not even use flash, but since it's so dark, I don't see any way around it.
First, I never used my ABs to light a whole venue.....The test shot below was taken (around 6pm) from the balcony with two AB800s on stands, only 7" reflectors aimed slightly above level and inward toward center. After seeing the bad shadows I nixed this idea....I'd probably need another set of them down on the floor level to eliminate or reduce this, and that's not possible. I only have 3 AB800s.
C/C would be appreciated.
