The larger an object is in a picture, the stronger it feels.

I see how powerful white is here because it shows up so strongly against dark backgrounds. The white is effective because it is used with restraint.

The center of the page is the most effective “center of attention.” It is the point of greatest attraction.

Mountains, slides, waves: all of these are diagonals in movement or in tension.

We see pictures as extensions of the real world.

The edges and corners of the picture are the edges and corners of the picture-world.

It means that any picture that emphasizes the diagonal—whether with shapes or colors or light or any structural element—feels dynamic to us, because the diagonal implies movement or tension.

equanimity,

All other things being equal, if we want to put more emphasis on an object, we tend to place it in the upper half of the page.
