Ok, its been a long time since I've done a wedding. I've been avoiding them, but I'll be taking pictures for a co-workers daughter this Saturday. They aren't too concerned about the photography and just thought it would be nice if I took pictures. The weddings is in the backyard of a historical building that is right near the town hall parking lot at 7pm so they will have parking lot lights off in the distance providing some light and they are planning to have candles and possibly some Lowes worklights. They will have about 80 chairs setup and the bride and groom will be on a small landscaped rise in front of the crowd.
I'll be taking pics while it is still light outside but during the ceremony what should I do. I could bring 2 high powered strobes on softboxes or umbrellas or beauty dishes and put them at the back of the chairs on either corner or I could just put my speed light with a ringflash adapter for something simple that works well. I don't want to be to disrupting during the ceremony. I have 85mm 1.2 for low lighting with ray flash fill or enough strobe power to make everyone get a tan.
All advice appreciated.
