selecting Pixels
Selecting pixels is the
key to manipulating portions of images. Without
selection, any adjustments, filters, or masks you apply would affect the entire
image. Photoshop has many different selection tools for use in different situ-
ations. In this chapter you'll learn how to choose the right tool for the job by
using marquees and lassos, selecting by drawing, painting and by color, and
finally, quick selecting and refining for the most efficient results.

selecting with Marquees
Marquees are windows that you drag across an image to select pixels. Marquees
can be square, rectangular, circular, or elliptical. Selection borders appear as
a series of dashed lines that slowly migrate along the edge. Selection edges
are called
marching ants
because of this uncanny resemblance.
