The gaffer is responsible for managing lighting, including associated resources such as labor, lighting instruments and electrical equipment under the direction of the
director of photography (DP, DOP or Cinematographer) or, in television, the lighting director (LD). The DP/LD is responsible for the overall lighting design, but delegates the implementation of the design to the gaffer and the
key grip. The key grip is the head
grip, in charge of the labor and non-electrical equipment used to support and modify the lighting. Grip equipment includes stands,
flags and
gobos. The gaffer will usually have an assistant called a
best boy and, depending on the size of the job, crew members who are called "set lighting technicians" or "
electricians", although not all of them are trained as
electricians in the usual sense of the term. ==Gaffer tape==
