I've been reading some about camera angle and how it impacts the interest and mood of the viewer. Orson Welles seems to receive much of the credit for being an experimenter with both low and high camera angle, particularly using the low angle to add a threatening feeling to the characters and scenes. We are seeing a huge resurgence in the high point of view, similar to what I first saw locally when the late Lloyd Moore did some remarkable selfie shots of him and friends way back in the film days (and when really wide lenses were really expensive). Lloyd used the Bird's Eye View point of view, though, being a directly overhead shot. The low angle is still relatively rare in still photography but seem very popular and very effective in snow boarding and surfing videos done with small waterproof cameras.
