The second unit I did was the use of the Square Marquee tool in Photoshop. I used this tool to make a design which I then turned in to multiple others. I used the liquefy tool to alter the design. These alterations were warp, bloat, pucker, and twirl. I also adjusted the colors of my design to create an inverted design, analogous design and a black and white design. After all of these alterations I created a design that communicated a global issue. This issue was global warming.
