132 ABSOLUTE BEGINNER’S GUIDE TODIGITAL PHOTOGRAPHY
The Absolute Minimum
Comparing Photoshop Elements and iPhoto is somewhat like comparing apples to
oranges. Both applications enable you to adjust photos, but Photoshop Elements is a
much more advanced tool. Elements includes resizing tools and transformation tools
that enable you to scale, rotate, and adjust perspective for distorted images. iPhoto is
essentially an image manager with basic retouching tools.
Regardless of which tool you use, keep these ideas in mind:
■ Image management is a necessary evil in digital photography. Images are
now easierto lose than they were when we used shoeboxes and three-ring
binders.
■ Photoshop Elements includes the same transformation tools as Photoshop,
which are Scale, Rotate, Skew, Distort, and Perspective.
■ All cameras import at 72 ppi. Images should be printed at 150–300 ppi. You
must resize the image after importing it.
■ Resampling an image should always be a last resort, especially if you need to
increase the image’s size. Rescan or reshoot if possible.
