Businesses providing creative artistic and literary work produce original material for clients, publishers, organisations or the public. This can include paintings, drawings, sculpture, photography, illustration, craft-based work, digital artwork, scripts, poetry, fiction, non-fiction and other written content. Some practitioners develop and sell their own work, while others take commissions or create material to a brief. Services may include concept development, research, drafting, design, illustration, editing and revisions, depending on the practitioner and project. Work can be intended for books, magazines, exhibitions, performances, websites, advertising, education or personal use. Customers usually agree the scope, format, delivery arrangements and permitted use of the finished work with the creator.
