IT HAS been seen that the position and tilt of the camera in relation to the subject greatly affects the way the viewer perceives that subject. A low angle viewpoint is the apparent short distance and below eye-line angle from which the camera views and records the subject.
Low angle shots increase height of a fore-ground short object and giving it a sense of dominance, the low angle shots are taken.
The background of a low angle shot will tend to be just sky or ceiling or space above the mid-ground objects. The added height of the object through low-angle shots inspires dominance to short fore-ground objects.
The inset photo of a twig on a rooftop has been taken from a low angle to look big and jutting into the sky.
