Having made the move recently from California to New Mexico, loving to shoot both states (and points in between), and having recently bought a Canon 5D Mark II, I was happy to have recently encountered Timescapes.org, who is currently working on a film about the area – Southwest Light – which is being shot timelapse with DSLRs such as the 5D. What makes some of these scenes particularly interesting is the motion control dolly they are using: A stepper motor is incrementing the camera's position between shots along a slide rail, combining the sensation of panning (a “dolly shot”) with timelapse – nice work.
The video above is a quick look at the dolly; the two videos below are Vimeo preview of what Tom and Timescales is doing with it. (Also visit the Mountain Light page on Vimeo for links to more “behind the scenes” videos about the shoot.)
