Question

How do high speed spy planes avoid motion blur in their photographs?

In: 51

Answer 1

Two things:

parallax: things far away appear to move slower. Imagine you are driving 60mph down the road. If you look out the side window the trees will be moving by very fast but the hill off in the background is not moving fast. Since a spy plane is taking photos from a high altitude everything it sees is moving slowly

shutter speed: cameras can set the shutter speed fast enough to eliminate motion blur
