I've had a request from a girl I kinda sorta know from work, for me to take pictures of her family. I'm SO nervous!!! I've only ever taken pictures for my own enjoyment, mostly of my LO and outdoors. Any tips for a productive, successful first shoot? Thanks!

P.S. There will be 5 total people. 1 couple with a kid, and her sister and her kid. And it will be outdoors
