origins from PICture and Element.

Pixels are the basic unit of an image displayed on a computer or
television screen or on a printer.

Dolly

Dolly is a cart which travels along
tracks. The camera is mounted on the
dolly and records the shot as it moves.
Dolly shots have a number of applications
and can provide very dramatic
footage.The name comes from the old
“dolly tracks” that used to be laid down
for the heavy camera to move along - very
much like railroad tracks

Most dollies have a lever to allow for
vertical movement as well. This movement
is also known as Pedestal move.

In recent times, dollies are being replaced with steadicams.
