    Fisheye lens project - model rocket in slo-mo

     

    Model rocket liftoff at 200 frames per second (about 1/8 slow motion), using a Traid 200V 16mm film camera with a Wollensak 3.7mm f/1.5 lens.  Filmed on a baseball field in Grayslake, IL in 2006.

     

    Jitter is due to intermittent-drive claw mechanism in camera.  You can't really run one of those at 200 frames a second, but Traid tried!  Faster cameras use more clever designs (pin-registration, rotating prism, etc.) but hey back in the 50's when this camera was made, this was quite the design.

     

    Camera puts a full circular image on film, but I have yet to find anyone who can digitize 16mm film all the way out to the edges of the frame (since normal 16mm movies don't need it.)

     

    I'm building an Estes Saturn V rocket so I can film it like this, and replicate all those old NASA Apollo liftoffs, where the "UNITED STATES" logo passes by the fisheye slo-mo camera on the launch tower...
