The Chapter 13 start file use has been prepared for you with an image of a balloon extracted from its background in a layer group that includes adjustment layers. This prepared file reduces completion time for those in a classroom environment, and reduces redundancy in the text. View this screencast to see how I used the Pen tool and a layer mask to isolate the balloon and make the color modifications within the "ballon-original" layer group. These methods are introduced in Section 3, Digital Manipulation and Fair Use.
