This document discusses the evolution of modern art in the late 19th and early 20th centuries. It explores how modern art shifted from traditional subject matter and styles with the rise of photography. Artists experimented with abstraction, collage, found objects, and non-representational forms. Figurative works also simplified forms and blurred spatial relationships. Artists questioned the definition of art and increasingly focused on the material aspects of painting over representation. Modern art reflected the technological changes and uncertainties of the time.
