Smooth for good, an invention that will probably change the way we look at sliders:
Sliders. Convenient, compact devices that let us achieve dolly shots easily and affordably. They have become very popular with HDSLR, but one of the biggest challenges when using a slider is to make a shot really smooth (=professional).
The smoothness and build quality of the bearings of the device is one factor and the technique of movement another that will affect our shot. There have been different approaches to make pocket dollys and sliders run smoothly, the most advanced devices are motorized and expensive, but here’s an approach that will probably revolutionize the way we look at sliders.
“Polly” is a device created by Thomas Kress from Germany. The idea is that a flywheel simultaneously accumulates the kinetic energy and stabilizes the movement.
