Your distance to your subject affects perspective. The field of view is controlled by your focal length.
So do you think about the focal length to select the type of image your trying to craft.
Its far to easy to stick a zoom on your camera and just zoom with your lens, but we should also zoom with our feet as this is what affects the perspective.
Spend some time with a prime lens or with your zoom set to a specific length, get to understand what look it gives you and how you can make it work for you.
