the farther from the middle and more isolated an object is, the greater its weight or attraction

When you have completed a picture, try cutting off various parts of it to determine whether you have achieved a balanced composition.

Space without detail may possess attraction by gradation and by suggestion.

A unit near the edge has more attraction than the same unit at the middle.

A unit of attraction in an otherwise empty space has more weight through isolation than when placed with other units.

In every composition the eye should cross the central division at least once. This creates equipoise or balance of parts.

If the questionable half is either cut off or greatly elongated, will the picture still survive without damage?

A perfect composition will not cause the viewer to turn his head to a false angle in the picture.

A picture should be able to hang from its exact middle

The mind hardly considers balance until it notes a complication of many units.
