The document discusses the conventions of film posters and compares the poster the author created to these conventions. It notes that conventional posters usually feature a prominent photo or image, typography suited to the theme that is easily recognizable, and lasting appeal/recognizability. They also often include reviews and present institutional information like the director at the bottom. The author then explains how their poster follows these conventions by using a edited central photo, custom but DIY-style typography, easily recognizable iconography and colors, relevant reviews, and institutional info at the bottom in a conventional font.
