channels . Photoshop also uses channels to store an image's color information. Un-
like layers, channels do not print. You use the Channels panel to view and work
with alpha channels.
A key concept in masking is that black hides and white reveals. As in life, rarely
is anything black and white. Shades of gray partially hide, depending on the gray
levels (255 is the value for black, hiding artwork completely; 0 is the value for
white, revealing artwork completely).
Getting started
First, you'll view the image that you'll create using masks and channels.
1. Start Photoshop, and then immediately hold down Ctrl+Alt+Shift (Win-
dows) or Command+Option+Shift (Mac OS) to restore the default prefer-
ences. (See “ Restoring default preferences ” on page 4 . )
2. When prompted, click Yes to delete the Adobe Photoshop Settings file.
3. Choose File > Browse In Bridge to open Adobe Bridge.
Note
If Bridge isn't installed, you'll be prompted to install it when you
choose Browse In Bridge. For more information, see page 3 .
4. Click the Favorites tab on the left side of the Bridge window. Select the
Lessons folder, and then double-click the Lesson06 folder in the Content
panel.
5. Study the 06End.psd file. To enlarge the thumbnail so that you can see it
more clearly, move the thumbnail slider at the bottom of the Bridge win-
dow to the right.
In this lesson, you'll create a magazine cover. The model for the cover was pho-
tographed in front of a different background. You'll use masking and the Refine
Mask feature to place the model on the appropriate background.
6. Double-click the 06Start.psd thumbnail to open it in Photoshop. Click OK
if you see an Embedded Profile Mismatch dialog box.
