The document discusses conventions of print advertising composition and representation. It explains the rule of thirds for composing frames, noting images should be divided into nine equal parts with focal points aligned along the four intersections. Depth of field is also covered, distinguishing between deep focus showing everything sharp versus selective focus picking out a particular sharp part of the frame while blurring the rest. The main activity instructs students to label an advertising print with terminology, annotate it linking to representation, exchange with peers, and individually write a paragraph analyzing representation using appropriate language and theory.
