High Angle
A viewpoint above the subject, looking downward.
Measured in
degrees
In depth
Looking down diminishes a subject and can suggest vulnerability or observation, and it replaces the sky with ground, which is usually more detailed. It also compresses a group into a legible arrangement, which is why banquet and crowd photographs are so often made from a balcony.
Examples in practice
A market photographed from an overlooking window resolves a chaotic crowd into a readable pattern of stalls and figures.
