I'm a relatively new photographer, certainly new to anything with profit involved, and seem to have been thrown into the deep end. A couple weeks ago, I forced* one of my best friends into posing for portraits so I could expand my portfolio. He and his mom loved the pics and she wants me to do family portraits for them. She's offered to pay me, which I'm entirely on board with, for obvious reasons. But I have no idea what I'm doing. It'll be mom, dad and two teenage boys (16 and 17). Everything I can find online is with little kids, so I have no clue how to pose them, or what will look "natural." I'm definitely interested in doing this, but could use some help with a jumping off point. *By "forced" I mean that I half-jokingly said "Dude, you need to let me take portraits of you," and he said "that would be AWESOME!" so we did the thing.
