Part I: Breezing through Basic Training 
for Photoshop users from every corner of the computer graphics field and 
from every corner of the world. People are doing some pretty amazing things 
with Photoshop, many of which are so far from the program’s original roots 
that it boggles the mind!
What Photoshop is designed to do
Adobe Photoshop is an image-editing program. It’s designed to help you edit 
images — digital or digitized images, photographs, and otherwise. This is the 
core purpose of Photoshop. Over the years, Photoshop has grown and devel-
oped, adding features that supplement its basic operations. But at its heart, 
Photoshop is an image editor. At its most basic, Photoshop’s workflow goes 
something like this: You take a picture, you edit the picture, and you print 
the picture (as illustrated in Figure 1-1).

 Basic Photoshop: Take photo, edit photo, print photo. Drink coffee (optional).
Whether captured with a digital camera, scanned into the computer, or 
created from scratch in Photoshop, your artwork consists of tiny squares of 
color, which are picture elements called pixels. (Pixels and the nature of digital 
imaging are explored in depth in Chapter 2.) Photoshop is all about chang-

at a time — to make your artwork look precisely how you want it to look. 
(Photoshop, by the way, has no Good Taste or Quality Art filter. It’s up to you to 
decide what suits your artistic or personal vision and what meets your profes-

shown in Figure 1-2: namely, correcting red-eye and minimizing wrinkles (both 
discussed in Chapter 9); and compositing images (see Chapter 10).
  It seems that every time a new version of Photoshop is released, it has 
at least one new feature that I just can’t wait to tell you about. Of all the 
great improvements in Photoshop CS5 (including 64-bit cross platform 
performance — more on that in a bit), perhaps the biggest Wow! factor is 
Content-Aware Fill. When you’re retouching and compositing, Content-Aware 
Fill can really help make your result look more natural and seamless. When 
you make a selection and press the Delete/Backspace key, the Fill dialog box 
pops up, offering you the opportunity to simply delete the content of the
