Adobe Photoshop CS3: Masks and Channels As Selection Tools

Photoshop uses masks to allow you to isolate and manipulate specific portions of an image. Think of a mask like a stencil - the cutout portion of the mask can be altered, but areas outside the mask are protected from change. Channels store different pieces of information separately, somewhat like layers. Learn how to use masks and channels to make your editing chores easier.

Here's what we'll cover:

  • Refining a selection using a Quick Mask
  • Saving selections as a channel mask for later reuse
  • Viewing a mask using the Channels Palette
  • Loading a saved mask and applying effects to the selection
  • Painting in a mask to modify the selection
  • Using the Extract command to make extremely intricate selections
  • Creating and using a gradient mask

Prerequisites: Completion of Adobe Photoshop CS3: An Introduction and familiarity with the Windows or Macintosh operating systems.
