One of the most common principles that videographers both on film and digital video look for is the Z-Axis. The Z-Axis, in contrast to the X and Y axis, is an angle of view that gives the action depth on the screen. The X axis runs from right to left, and the Y axis goes up and down. The Z-Axis is different from these two as it runs from one corner to the opposite corner. The idea is to get action that is coming toward or away from the camera to run slightly from one of these corners to the opposite one. An example of this is if a person is riding a bicycle toward the camera you do not put the camera head on the subject, but instead slightly to the right or left of their path of motion. That way they are not only coming toward the camera but also moving either left or right. This make the image pop out of the screen and the action suddenly becomes more engaging.
