Youre welcome rusty. I think the op will do fine. I am by no means a pro, but as the guy in the group with the "big" camera I'm put in this situation often whether it is friends, co workers, etc. I'm generally very happy to do it especially since folks who are turning to me are generally looking to spend less than $1000 for a photographer for their big day. Seeing the results of that kind of a budget I know I will no only care more than another photographer and will try my best. do I miss things, yes, but I put the time and effort into it to make it a good day for them. Expectations are set low, i inform them id much rather enjoy the day with them, but i also don't want them hiring a hack who doesn't care. all I ask of the couple is to cover my backup gear rental fees and a nice bottle of wine.
