CS203 Digital Graphics 1 (Photoshop)

Section 3 - Image Basics


In this section you will learn the basics of creating, opening, resizing and saving image files in Photoshop. Some of the topics are split into multiple videos with at least one video that will show the basics without explaining all of the details. It will be enough for you to use the tools, but won't drown you in detail.

There are also videos that will cover all of the options as well as providing a description of what all the different options mean. These videos are marked as Advanced, and they are optional. That is, you won't need to watch them to learn enough Photoshop to pass the class, but they all have good information that you will want to learn sooner or later if you want to make a career of working with Photoshop.
