I just watched the video again, so much good info in it! In addition to what @carlianne said about things being perfectly symmetrical being less interesting, it seemed to be a recurring thing that people use the point of view of a drone hovering 20 feet above the ground as a default. It could be that a personâs eye line is lower than first expected.
When Iâm standing outside, my eyes are only 5 feet off the ground. So if my front doorâs knob is also 5 ft off the ground, that will be at the horizon level. Anything taller that will appear above the horizon. My home is like 50 ft tall, so almost all of it is above my eye line/ horizon. The numbers arenât important, but having an idea of where a humanâs eyes would stand could be good to keep in mind.
I think the idea is to be purposeful about the POV to fit the narrative. In the video they commented that some looked like establishing shots for a sitcom intro, so if thatâs what youâre going for, the 20 ft helicopter hover camera may be what you want. If youâre a little kid walking up to a haunted house, exaggerating the low angle may be scarier. If youâre spiderman on the roof of a skyscraper, a high camera angle from above could be exciting. If you are going for something like a folksy style, linear perspective may just not be that important, and forcing the drawing into vanishing points could be distracting. I think deciding the effect you want comes before deciding the camera position.
