There are several ways to show balance in your photo. The obvious is symmetrical with the right side mirroring the left (or top vs. bottom). But it can also be achieved through asymmetry, tone, or color. (Here’s a good explanation that goes into it further. CLICK HERE )
In my example, I have used color to balance the massive oxen that take up two-thirds of the space against the one-third occupied by the driver on the right. Though he is much smaller, his bright blue jacket draws the eye and counter-balances all the brown tones in the rest of the photo.
