I will be shooting a wedding in a few weeks and one of the things I thought would be a good idea is to wirelessly fire some strobes as I take flash photos at the reception. These strobes would be positioned in unobtrusive locations in the hall just to give a bit more light in the backgrounds. So I would like to know if this is something I should do, and if so, what I will need to do it. I know I can adjust my camera's settings to make the ambient exposure brighter, but I want to be prepared in case that doesn't work out. Anyway, is this a recommended thing to do? I did see it done at a wedding I attended and it seemed like a good idea. Right now i own a Canon 420ex, 3 strobes/umbrellas, cheap e-bay transmitter/receivers. Is this too much to deal with considering the short time I have until the wedding?
