Depict, portray, sketch imply a representation of an object or scene by colors or lines, or by words. Depict emphasizes vividness of detail: to depict the confusion of departure. Portray emphasizes faithful representation: We could not portray the anguish of the exiles. Sketch suggests the drawing of the outlines of the most prominent features or details, often in a preparatory way: to sketch the plans for a community development.
In painting and sculpture, the term representational art usually refers to images that are clearly recognizable for what they purport to be, such as a human figure, a banana, a tree, and so on.Such images need not be true to life.f course, they do 'interpret' what they see-hence no two painters will paint a scene in identical fashion-but their primary aim is to observe and reproduce the object(s) in front of them. Thus, for example, plein-air painting-an approach popularized by 19th century Impressionists-is almost always representational.
