The document describes the process of creating an ancillary text poster in Photoshop. It discusses setting up a new Photoshop project with the appropriate dimensions and resolution for a poster. It then explains how to import images and text, adjust their size and position on the poster, and add effects like changing opacity. Tools used include adjustment layers, selection tools, and transform tools. The final poster is shown, along with a reflection that this was the weakest of the three texts created despite Photoshop experience.
