Radial Balance

This picture displays radial balance, because it not only has the three main

lightbulbs, but it also has all the delicate inner rings in each light. It kinda 

looks like Saturn. This is unrelated, but it also shows depth of field, because 

the light on the left is focused and sharp, while the one on the right is blurry

and out of focus. But all the round edges do make it qualify for radial balance.
