In a
theatrical production, it is the lighting designer whose job it is to decide what
lights they will be using, which
lights will be going where, where they will be
pointing, what
colour they will be, and any
special effects that there might be. This job involves quite a lot of
artistic ability, as well as both the
knowledge of what
lights are available and how to use them, and the ability to take what the
director wants and convert it into a
design.
On a smaller
show, this
role may be
combined with both the
chief electrician, and the
lighting operator, and just have one
lighting person running everything, but on larger
shows, it is much more normal for the roles to be split up.
