As a portrait photographer, we are constantly thinking about the larger picture. Besides posing your subjects in flattering poses with arms and hands relaxed and getting more close ups, I generally like to shoot a few atmospheric portraits with the landscape as the primary focus. This way, when designing a book or giving a client some ideas of large wall canvases, its best to have landscape so the portrait is not just a face. I also make sure I am framing in the camera with the rule of thirds in mind. Not everything needs to be centered. I have attached some examples ..some are vacation photos like the little kids with pink inner-tubes and my son in the giant bamboo..
