Balance is created by an arrangement of elements (including space) that is visually satisfying. Symmetrical and asymmetrical designs can work. Sometimes a lack of balance is easier to notice.
Some photographers use “a rule of thirds” to create balance in a photograph. Visualize the frame as thirds of the space—vertical and horizontal—and place focal elements in these thirds.
This photograph is an example: the youth is positioned in the left third of the vertical space.
The subject in the right two-thirds of the frame is balanced by the space on the left.
