Production designer

A production designer is the head of the art department. They are ultimately responsible for producing the overall look of the physical elements seen in an episode. They help the director of photography and director choose locations for out-of-studio filming. They are also responsible for the practical manufacture of most of their designs, either in-house or by prosthetic or CGI specialists. They are one of the key personnel in the pre-production process, and one of the first people to be involved in the making of an episode. Since the art department is comprised of many sub-departments, the production designer also has managerial responsibilities over a large number of the people working on a programme, equivalent to that of the production manager or the post-production supervisor.

Specific duties
Fully describing all the things under the control of the production designer would be difficult, as they touch many aspects of the production. However, there are certain key tasks that can be highlighted. It should be pointed out that many of these tasks are completed by their own departments, but all of those departments come under the aegis of the production designer.
 * Concept artistry for sets, props, characters, models, signage, images on the screens of in-scene computers and other graphical elements
 * Overseeing prop construction and continuity
 * Overseeing set construction
 * Location scouting (usually done in conjunction with other senior staff, such as the director and director of photography)
 * Overseeing the costume department to make sure their designs harmonise with sets and props
 * Acting as a "governor" to the imagination of the writer by providing a budget for achieving the script as initially written. This can greatly affect the final form of the scripts.
 * presenting ideas to others involved in the production, such as actors and camera operators.
