I am not going to offer any lighting advice because I would be in about the same boat as you if someone asked.


But I see you have two options:


1, You have been asked to do this for free, and hey, it will give you a chance to practice and play so that could be fun. After all if you mess up, no one lost any money on it.


2, If you want out you have several outs.


a. Your first out is that yes obviously the 580ex is very harsh on camera, you can tune it down and such but, your wife does not know this. You just need to tell her that she will need to help you during the wedding and carry a monopod with your 580ex off camera so you can get the best lighting. This should deter her.


b. Your second out is that obviously you need to buy a large amount of new equipment. Two things can happen here, your wife says "never mind" or you end up going in debt and owning a lot of new fun equipment (debts not good, but new equipment though...)


Good Luck and Have Fun
