One pose can yield you many different results if you give yourself options when shooting. I hardly switch out of a pose without shooting at least two variations of it. Take this one for example: I adjusted the sisters into their pose with the aim of showing connection and I was able to get three entirely different images in a matter of seconds without my subjects having to move positions.
The first shot.
The candid: using my fake-out method.
The closeup: bringing the heads closer together and shooting slightly above eye level.
