The document discusses the conventions used and challenged in a poster, magazine cover, and trailer created to promote a film. For the poster, a conventional layout with a central image and title is used, while an unconventional solid black background helps the image stand out. The magazine cover develops conventions by positioning the image and title differently but keeps a simple structure. The trailer develops conventions through dark, barely visible scenes and breaks conventions by lacking voiceover or dialogue. Conventions are mostly followed for familiarity but also developed and challenged to suit the styled products.
