Reading: Viewpoint in Portraiture
It makes a lot of sense: the vertical angle at which you take portrait photographs conveys subconscious messages about the relationship between the viewer/photographer and the the subject/model.
- Straight on: an equal relationship between the viewer and the subject
- Slightly above: can make pleasing shots, as the eyes appear larger. The sitter can appear passive or (with extreme use) submissive.
- Slightly below: subject appears dominant, important, or confident. Needs to be used with care, though – it can also make the subject look scary!
