Rule of thirds

The frame divided in thirds, subjects placed on the lines and crossings. Composition's training wheels, and still its useful default.

The rule encodes a real observation: frames divided unevenly feel inhabited, centred frames feel addressed. Eyes on the upper-third line, horizons on one line rather than the middle, subjects at the crossings, the defaults produce livable compositions with almost no thought, which is precisely their function.

Their limit is that no rule composes: thirds are where you start, not where you arrive. Centring, when chosen, is a statement the rule cannot make, symmetry, ceremony, confrontation, and the strongest frames often obey a logic of weight and gaze that thirds merely approximate. Learn it thoroughly; obey it until disobedience has a reason.
