Each lesson includes step-by-step instructions, lesson  les, and video tutorials, all of which

A note about color warnings
Depending upon how your Color Settings are con gured, there may be times when you will
receive a Missing Pro le or Embedded Pro le Mismatch warning. Understand that if you reset
your preferences before each lesson (without restoring your color settings) you should not
see these color warnings. This is because the default color setting of North America General
Purpose 2 has all warning check boxes unchecked.

If you do receive Missing Pro le and Embedded Pro le Mismatch warnings, choose the Assign
working option, or Convert document’s colors to the working space. What is determined to be
your working space is what you have assigned in the Color Settings dialog box. Color Settings
are discussed in more detail in Lesson 6, “Painting and Retouching” and in Lesson 7, “Creating
a Good Image.”

Loading lesson  les
The Photoshop CS4 Digital Classroom DVD includes  les that accompany the exercises for each
of the lessons. You may copy the entire lessons folder from the supplied DVD to your hard drive,
or copy only the lesson folders for the individual lessons you wish to complete.
For each lesson in the book, the  les are referenced by the  le name of each  le. The exact
location of each  le on your computer is not used, as you may have placed the  les in a unique
location on your hard drive. We suggest placing the lesson  les in the My Documents folder
(Windows) or at the top level of your hard drive (Mac OS).
Copying the lesson  les to your hard drive:
1 Insert the Photoshop CS4 Digital Classroom DVD supplied with this book.
2 On your computer desktop, navigate to the DVD and locate the folder named pslessons.
3 You can install all of the  les,
or just speci c lesson  les. Do one of the following:
Install all lesson  les by dragging the pslessons folder to your hard drive.•
Install only some of the  les by creating a new folder on your hard drive named •
pslessons. Open the pslessons folder on the supplied DVD, select the lesson you wish to
complete, and drag the folder(s) to the pslessons folder you created on your hard drive.
Macintosh users may need to unlock the  les if they are copied from the accompanying disc. This
only applies to Mac OS computers. After copying the  les to your computer, select the pslessons
folder, then choose File > Get Info. In the pslessons info window, click the You can drop-down

menu labeled Read Only, which is located in the Ownership & Permissions section of this
window. From the You can drop-down menu, choose Read & Write. Click the arrow to the left
of Details, then click the Apply to enclosed items button at the bottom of the window. You
may need to click the padlock icon to change these permissions. After making these changes, close
the window.
