One of the keys to mastering digital image manipulation is efficiently and effectively using the selection tools to select portions of an image that you wish to manipulate. Let’s get started with some basic tools and techniques to select portions of an image.

Objective:

Students will be able to select the right tool for any selection task by practicing with a range of different tools and selection tasks within a composite image so that they can produce more efficient and effective digital image edits.
