Okay, so here's what went down today;
I did end up getting paid $150, because she decided that she actually did like my photos once she saw some that I'd taken.
I didn't get any of the files, but she's going to send me through some of mine...as to which ones I don't know what I'll end up with, but it's better than none.
I learnt that some wedding photographers aren't as good as their reputation...she had no idea how to get young children to pose for her, so I did all the young kids photos [thank you 2 years of santa photography]. And the bride wanted more candid, happy type photos, yet the photographer was trying to get people to stand and pose exactly how she said, and would get grumpy when the moved slightly.
The bride pulled me aside at the end, and got my details, so she can pass it on to friends etc. and she also said she would have preferred for me to have been doing all the photos as I was so much more relaxed.
So all in all, it was a good learning experience, I'm glad I ended up getting compensation for my time & petrol, and I think I did well with building up rapport with the clients
