I'm having my friend be a backup photographer for my wedding. I'm still hiring a pro since she's never done it before, but I know that I like her style and you can never have too many wedding pictures. (Especially when you're obsessed with photoshop like I am.

) Anyways, are there any suggestions as to how much I should pay her? I'd ideally like to have her come to the rehearsal the night before and cover that too, and hopefully have her taking pictures starting at the very beginning with the hair appointment on the day of. I don't know if that's too long to ask her to cover, though. (Though she doesn't live in town so I don't know that she'd be doing anything else anyways.) I don't want her to feel like I'm taking advantage of her or anything like that. (Suggestions on that too?) For her to get to the wedding location, it's either an 11-hour car ride or a $450 plane ticket, if you think that should affect how much I pay her. Is there a tactful way to request part of it as her gift to us? Ideally I'd like to pay her whatever, but my budget is kind of limited, so I'm trying to find a medium between her still feeling appreciated and not undervalued and me not going broke. I'm open to any and all ideas. =\
Thanks in advance for any suggestions!
