1. Job definitions in the media
Director- ‘A film's director is involved in every basic stage of its production. Being a director
requires the ability to visualize how a script will be acted out, and the perseverance to see a long-
term project through to the end. Generally speaking:
A director works with the producer and the screenwriters to determine the best way to visually
present the ideas being developed. An experienced director knows which cinematographers and
set designers will be best suited for a given project, or who are simply most comfortable for him or
her to work with, and will often have the final word on who's hired. Some directors will assert very
tight control over all aspects of a production, while others might; for example, give the
cinematographer a lot more free reign to decide about a film's "look."
When the movie's being filmed, the director works with the actors on interpreting their roles, a bit
of tutelage that will vary from director to director, with some offering more input on performance
than others. The director also decides when a scene has been filmed enough times and of course
calls all the (literal) shots behind the camera.
During the post-production stage, a director usually helps the editor put together the best movie
possible from amid the vast store of footage and camera angles typically shot on a movie set. He
or she also sits with the film's music director to work out what music will be played in the
background and to help explain the themes that should be suggested by the musical score.’

My understanding of the role of the director is that they have to work closely with the camera
operator in order to show what the best angles would be and best ways to film things, they give
actors notes tips on how to act like there character more, like how to stand and facial expressions.
Camera man/woman – ‘the camera operator is responsible for physically operating the camera
and maintaining composition and camera angles throughout a given scene or shot. In narrative
filmmaking, the camera operator will collaborate with the director, director of photography,
actors and crew to make technical and creative decisions. In this setting, a camera operator is part
of a film crew consisting of the director of photography and one or more camera assistants. In
documentary filmmaking and news, the camera is often called on to film unfolding’

2. The camera operator has to manually work the camera to get the best shots and angles, although
getting the directors view on thing they have to put their experience into it to get the best results.
This could be tricky as you have to get it as close as to what the director wants as possible.
Boom Operators- ‘A Boom operator is an assistant of the production sound mixer. The principal
responsibility of the boom operator is microphone placement, usually using a boom pole (or
"fishpole") with a microphone attached to the end, his aim being to hold the microphone as close
to the actors or action as possible without allowing the microphone or boom to enter the camera's
frame. Often in television studios, the boom operator will use a "fisher boom", which is a more
intricate and specialized piece of equipment on which the operator stands, allowing precise control
of the microphone at a greater distance from the actors. He will also attach wireless microphones
to persons whose voice requires recording. Boom poles are usually manufactured from several
lengths of aluminium or carbon fibre tubing, allowing the boom to be extended and collapsed as
the situation requires. Some poles have a microphone cable routed through the inside of the pole,
which may be a regular cable protruding at the bottom end, or a coiled cable that can extend with
the pole, connecting to a socket at the base into which the operator plugs the microphone cable.
The ideal boom pole is lightweight and strong, supporting the weight of the microphone on the
end while adding as little weight as possible.’

A boom operator will try to get a microphone as close as possible to the actor without being in the
frame. This can be challenging if the scene is on the move and you have to balance it wile moving.

3. Lighting technician - ‘Electrical Lighting Technicians (ELT) or simply Lighting Tech., are involved
with rigging stage and location sets and controlling artificial, electric lights for art and
entertainment venues (theater or live music venues) or in video, television, or film production. In a
theater production, lighting technicians work under the lighting designer and master electrician. In
video, television, and film productions, lighting technicians work under the direction of the Gaffer
or Chief Lighting Technician whom takes their direction from the cinematographer. In live music,
lighting technicians work under the Lighting Director. All heads of department report to the
production manager.’

A lighting technician helps establish the best kind of lighting to make the scene, for example if it’s
sad then it might be darker. They help represent moods of characters as well by selecting a certain
level brightness/darkness which represents a characters emotion.
