Sophie Canning describes the process of creating her film magazine cover. She experimented with different fonts and chose one that was bold and clear. For the main image, she edited a photo in Photoshop to create the desired effect of a woman looking through a door. After creating a layout, she refined her drafts by adjusting placement of images and text, changing colors, and getting feedback from peers. Her final draft effectively conveyed the horror theme while following magazine design conventions.
