The rule of thirds is widely regarded as the most essential composition technique when taking aesthetically pleasing photographs. Viewers' eyes are believed to be drawn to imaginary lines that divide photographs into thirds, as well as the intersections of these lines. The meerkat above sits upright, its body curving along the right and bottom thirds of the photograph. The vulture below also satisfies the rule of thirds, as its head falls along the upper and right thirds of the photograph.
