A couple of the many rotating objects I've been shooting for my latest CanonGate Books short film. As described in the earlier post, I'm using a geared down stepper motor which can be controlled from my PC (using a Stepper Bee motor controller card).
My initial plan was to shoot these all these rotations as stop motion, but with motor control and the Canon 550D's HD video recording, I was presented with the opportunity to shoot these as continuous live-action. I set the motor to do just over a full rotation at quite a slow speed, knowing that I'd be able to edit and time remap the footage later... This simple rig works pretty well; super-smooth results and a bunch of time saved.
