This is always a really tough spot to be in. For our wedding we are on a pretty tight budget and ran into problems with photographer budget. We did invite a set of our friends, a husband and wife, to our wedding. She is a photographer, just brand new out of school and amateur and had only shot a few weddings. They responded saying they were coming to our wedding, so I thought I would just suck it up and let her be our photographer, although I really wanted those amazing pictures, which Im not sure she could have delivered. It would have been an amazing opportunity for her to expand her portfolio ect. It turns out she ended up getting pregnant and they are unable to attend our wedding so it made choosing a photographer a littl easier. We ended up going with a local Jamaican photographer, Merrick Cousley, as we liked his photos and fit our budget. We did look into bringing one from Alberta, but it was going to be to much money.
In my opinion it is definately worth it to splurge on photos. It puts you in a really tough spot for your family memeber. Maybe you could have her do some other photos, like engagement photos or something like that so she can still build her portfolio. I say go with the husband and wife, thats an awesome price!
