Studio arts are a subset of visual arts, in which artists manually manipulate media to produce a representational or abstract image. They include the classical drawing, charcoal, watercolor, sculpture, pastel, and mixed-media techniques.
There can be argument if photography is part, and it is most fair to say "fine art photography" is indeed a studio art, while scientific and industrial photography are not. Cinema and video are probably outside the discipline.
Design and building sets for performing arts is outside scope.
Art therapy makes use of studio art training for the therapist, and techniques for the clients.
