Capturing a view from top to bottom

Capturing view from top to bottom gives a sense of depth-of-field.

Top to bottom as in right angle to the horizontal plane. Or, about that view point in an steep angle to flat ground.

For example, at high floor looking down to the ground level.

The sense of depth-of-field refers to bokeh. Blurry background, subject in front or atop is sharply focused.
