Camera dolly

The move is the reason it survives. A camera travelling through space, with foreground and background shifting against each other, reads as far more expensive than anything a zoom can imitate. Studio dollies run on laid track, doorway dollies roll on the floor, and a skateboard dolly costs almost nothing.

Distinct from the kit creators usually own. A slider gives a short move measured in centimetres, a gimbal gives a floating walking shot with a drift no gimbal fully removes, and a dolly gives a long move that stays perfectly level.
