Old photos- Why do cars look like they are leaning forward at speed?

    Yep, its a frequency thing.

    Some turntables used to have squares pained or etched along their sides, so you could precisely tune the RPM with a lightsource that worked on the Hertz frequency of the electricity.

    Nope.

    But nice try.

    Since the wheel doesnt go out of round while its turning, it photographes round.
    No matter the RPM.

    The old fashioned shutter does cause the leaning forward effect.

    The people and trees leaning the other way was caused by panning the camera with the moving racecar.

    If they are both leaning ( in opposite directions ), then the panning want fast enough to keep up with the car...


    Edit.

    Just realised I replied to a post thats a couple of years old.


    OK...

    I guess he's off the hook for that Intro. :rolleyes:

    In one of the new Ford truck commercials the wheels appear to be not turning.

    My all time favorite photo in this category is the Cunningham at Bridgehampton.

    Ansel adams talks about this in one of his books, either camera or print.
     
  10. Sounds like the same phenomenon that made the spokes of the wagon wheels look like they were turning backwards in old Westerns.
     
  11. Tom Fritz and Robert Williams as well as other artists depicted speed to an other wise stationary painting to resemble the vintage photo's taken during a race.
