Person responsible for setting up and orchestrating
light settings during a show. You know, who to shine a
light on at specific lines/times.
Fact, these people usually know more about the ins and outs of the
show/
movie/
theater-set than anyone else, except maybe
director/
producer. They are obligated to know most of the script,
synchronize timing intervals, have a deep knowledge about
photography and have to work close with
stylists as well, in order to make shots appear good and bright.
Oh, and they make
minimum wage.
