Emphasis and Focal Points

This image demonstrates emphasis of one-element.  Although the swimmer might be considered the focal point, I believe it's the cityscape. I say this because the wording above the image attracts your eye more than the swimmer. Found on Bing.

This image represents emphasis by contrast, because the rest of the faces are yellow and they have smiles while the red one has a sad face. Found on Bing.

This image has an emphasis on isolation.  The dancers to the right seem to be the focal point, while the single dancer to the left is isolated from the group numerically and with a bright light. Found on Bing.

This image demonstrates emphasis by placement.  The fire-hydrant is the focal point because when you look at the hydrant your eyes move to the tree then to the building and eventually to the yellow post and back to the hydrant. Found on Bing.

This image has no focal point. It is almost like splatter paint.
