Whenever your subjects are moving in a direction, a basic rule of photography is to leave room in the direction the subject is moving. This rule is important because the viewer’s eyes are naturally drawn from the subject to whatever the subject is looking at or facing. If the subject is facing the edge of the frame, it leaves the viewer wondering where the subject is looking. Furthermore, if the subject is moving toward the end of the frame, it leaves the viewer wondering where the subject is going, leading the attention off of the image. Lastly, if the subject is moving toward the edge of the frame, the subject can seem confined and enclosed. As always, showing is more effective than explaining, so as you view these images, imagine how they would look if the subjects were cropped at the other end of the frame.
