First off this is not an add, I shoot weddings but that is all I will say here.
I see a lot of folks price shopping for photography, especially wedding photography and I found this great article that should help brides to be (and actually anyone looking for a photographer)
check it out Offbeat bride
Basically all the questions you should really ask your photographer but don't think you can, as a photographer myself I would say..... ask!
If you don't ask you don't get! If you aren't sure about something chances are your photographer has been asked your question a lot, and even if not they will know the answer.
