Grow and Expand. You may think they do the same thing, but there's a slight, important dif-
ference between them, as
Figure 5-19
shows:
▪
Grow
(Select→Grow) moves your selection outward to include more similar, contiguous
colors, no matter what shape your original selection was. This command doesn't care
about shape; it just finds more matching contiguous pixels.
▪
Expand
(Select→Modify→Expand) preserves the shape of your selection and just en-
larges it by the number of pixels you specify.
▪
Similar
(Select→Similar) does the same thing as Grow but looks at
all
the pixels in your
image, not just ones adjacent to the current selection.
▪
Contract
(Select→Modify→Contract) shrinks a selection by the number of pixels you
specify.
