BTS: Photographing a Ferrari With A "Portable" Car Rig
Nigel Harniman is known for his car shot and there is a good chance you've seen his work if you've seen any car ads lately.
His recent shows some of the effort that goes into a car rig shoot. The setup involves a suction mounted carbon fiber pole, a pulley system and a drool-over ALPA, Phase One and a Schneider lens combo.
If you take a look at the video you'll see that the shot was taken with a 30 seconds exposure, still remaining razor sharp.
Nigel was also king enough to put up a quick post-processing-lapse that shows how the image was processed.
P.S. If you want to try that yourself, but am working with a more cough limited budget, you can DIY a similar, yet not as fancy rig.
