Kress & Van Leeuwen - Angles in visual grammar

in today's class, I have to find some information about angles in visual grammar.
here's some information that I got from the book of Kress & Van Leeuwen:

Horizontal angles
These suggest different links of involvement in relationships between the represented person(s) or participants and the viewer.

frontal angle

• frontal angle – suggests viewer involvement with the person or objects in the image

oblique angle

• oblique angle – suggest viewer detachment with the persons or objects in the image (Kress & van Leeuwen 1996)












Vertical Angle
These suggest different links of power relationships between the represented person(s) or participants and the viewer.

high angle

• High angle – the viewer is looking down on the represented person, putting the viewer in a more powerful position

low angle

 • Low angle – the viewer looks up to the represented person, putting the viewer in a less powerful position

eye level

• Eye level – the point of view is one of equality with no power difference involved (Kress & van Leeuwen 1996.)
