The document describes how a Photoshop assignment was completed to create a composite image for a unit plan on energy. The author took two pictures - one with superhero logos and another of the Justice League - and used various Photoshop tools like layers, eraser, color range, and color absorber to extract symbols from the logo picture and place them on the chests of the Justice League to represent different types of energy. Filters were also applied to reshape the symbols and make them fit seamlessly on the superheroes' chests. The final composite image combines the pictures to show the Justice League as "Super Energy League".
