A charge artist (or charge scenic artist) leads and oversees the painting of stage, film or television scenery.
The charge artist's responsibilities include methods of reproduction of color, texture, preparation and ageing of all surfaces.
The charge artist interprets the scenic designer's technical drawings and paint elevations, and with a crew of journeymen scenic artists, brings them to life on the actual scenery.
The charge artist is also responsible for the budgeting of the finished sets along with the production designer and the art director.
