Steadicam is a brand of camera stabilizing mount for motion picture cameras that mechanically isolates it from the operator's movement. It allows for a smooth shot, even when moving quickly over an uneven surface. The Steadicam was invented by cameraman Garrett Brown and was introduced in 1975.
Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that used to view the sequence. When played at normal speed, time appears to be moving faster and thus lapsing. For example, an image of a scene may be captured once every second, then played back at 30 frames per second. The result is an apparent 30-times speed increase. Time-lapse photography can be considered the opposite of high speed photography or slow motion.
Processes that would normally appear subtle to the human eye, e.g. the motion of the sun and stars in the sky, become very pronounced. Time-lapse is the extreme version of the cinematography technique of under cranking, and can be confused with stop motion animation.
A follow focus is a focus control mechanism used in film making with film cameras and in television production with professional video cameras.
It is ergonomic rather than strictly necessary; in other words it does
not contribute to the basic functionality of a camera but instead allows
the operator to be more efficient and precise. It is usually operated
by a focus puller
(often called the 1st assistant camera, or 1st AC) but some camera
operators prefer to pull their own focus (the act of changing focus is
called "pulling" or racking focus)

Cinematography is writing with light in motion and the cinematographer is the principle author of this literature. When making a film, the cinematographer translates the vision he or she shares with the director and the production designer onto film. It has been truthfully said that the cinematographer is the co-author of any film.
