Camera Slider
A short track on which a camera moves smoothly in a straight line.
Measured in
cm
In depth
A slider adds parallax, which is what makes a shot read as three-dimensional: near objects move across the frame faster than distant ones. Even fifty centimetres of travel transforms a static interview or a time-lapse, and motorised versions allow the slow, precise movement that a hand cannot sustain.
Examples in practice
A 60 cm slide across a foreground branch gives a landscape time-lapse a genuine sense of depth.
