In cinematography, a low-angle shot, is a shot from a camera angle positioned low on the vertical axis, anywhere below the eye line, looking up. Sometimes, it is even directly below the subject's feet. Psychologically, the effect of the low-angle shot is that it makes the subject look strong and powerful.

It could be simply put as an angle closest to the floor and looking up towards the subject.
