Kennen wir so womöglich alle aus unseren Kindheitserinnerungen, wenn wir hinten im Auto saßen und die Laternen, die nahe an den Straßen standen, immer sehr viel schneller an uns vorbei zu rauschen schienen, als die, die weiter weg standen.
The illusion that speed decreases when zoomed is „because when one focuses on an inner portion of the movie, the optic flow angular speed is slow, and appears to fill one’s entitle visual field, which is consistent with overall lower forward speed.
Note: The more zoomed, the more densely packed the overhead rigging appears. So, even though you appear to be moving forward more slowly when zoomed in, the actual rate of rigging flowing by remains constant, consistent with same forward speed in all conditions.
