Radial, symmetrical, asymmetrical
Asymmetrical balance is achieved when both sides of a room are not identical but the room still acheives balance. The room in the image is asymmetrical because it is not identical on both sides. For example there is not a clock on each side, but there is something the same shape as the clock and it balances out with the clock.
Radial balance is achieved when the balance is in a circular pattern. This picture has radial balance because it is in a circular pattern. The middle of the light is a circle and the lights that go around it are in a circular pattern.
Symmetrical balance is achieved when both sides of a room are identical. This image represents symmetrical because it is the same on each side of the photo.
My Favorite Type of Balance
Symmetrical is my favorite type of balance because it is even on both sides. I also feel like it is the easiest because you just have to make each side identical.
