I've been asked to shoot a wedding at the Sea Lion exhibit at the Audubon Zoo next month. I won't be able to get in to see the location for another 2 weeks, but I have been told by the groom that it is dark. I'm hoping that both cameras will be close enough to the bride/groom that we can just use on camera lighting, but if we aren't, are there any suggestions? I was going to start looking for some kind of flood light that was DC powered. I'm going to need the fixture, stand, battery and sand bag. Any thoughts/suggestions?
