Webster defines perspective as:
the technique or process of representing on a plane or curved surface the spatial relation of objects as they might appear to the eye
Another definition is the interrelation in which a subject or it’s parts are mentally viewed – also known as “Point of View”.
What does this mean in photography terms? In its simplest form, perspective is all about changing the camera’s position and or angle to get a different point of view. When photographing my kids I like to think of this as “seeing what they’re seeing”. Kids tend to by very short people; closer to the ground then most of us. If we photograph them from our full heights as adults we are seeing what we see and we will generally get a nice view of the tops of their heads. Bring the camera down a couple feet by squatting or even laying on the ground and you will gain a whole new perspective into your kids vacation activities.
