02 Aug From 1000ft above something should be perceivable …
A little note in terms of movement exercises: Most of the time, the viewer tends to start very high up at altitude. To get a comparison of how far you can actually look from such a height and how large the field of view is, here are a few shots from the cockpit of a small aircraft flying at such heights.
Altitude: 2000 ft (approx. 600 m)
Altitude: 1500 ft (approx. 450 m)
Aerial view at around 500–1000 ft (approx. 150–300 m)
Aerial view of a landscape from approximately 2000 ft (approx. 600 m)
View from above at approximately 500 ft (approx. 150 m)
