Look for a simple distraction free background such as evergreen trees, a stone wall, fence row, etc. Place you subject 5-10' in front of it, tell a few jokes, relax and snap away. If the background is brighter than the subject, meter for that and use your flash for fill in. Dial down the flash exposure if using on-camera flash to what you need. Have fun and enjoy learning, most likely your subjects will love the pictures and you will take tons of them before you realize. Someone creative can find a doorway and use up their flash card in that one location.
Do be prepared with what kind of poses you'd like to see even if you take a cheat sheet, they may have a few of their own.
Good luck and post the shots.:thumbup:
