Elements within an image interact with each other and can be said to form a balance around the centre of the image. These elements don’t necessarily need to be actual objects, they can also be things such as the background, groups of colours, or lines etc.
Below is a set of images I’ve taken showing the original image, an image identifying the elements that contribute to its balance and then a depiction of the overall balance of the image.
The images above, have all been chosen because they demonstrate the idea of balance quite well. Most of the pictures do focus on specific objects which makes choosing the elements that contribute to the balance of the image easy. However, the second image (the misty landscape scene) has the main focus point (the largest tree) to the left of centre, roughly a third of the way into the image. Balance is achieved in this image between the main object of focus and the remaining background.
