How Lenses Affect Speed Perception

How Lenses Affect Speed Perception

We shoot a lot of video inside of cars looking out the windshield. But the in-car footage often makes it look much slower than it felt zooming around the track. After watching this clip from Akiyoshi Kitaoka, we realize just how much of a difference having a wide angle lens makes when it comes to the perception of speed.
