Lesson 9 |
In this lesson, you will learn how
to use the Magic Wand tool to select
areas based on a similarity in
color. |
|
|
|
Introduction |
Magic Wand tool selects areas based
on a range of color similarity. This
tool is inaccurate, however it is
convenient and useful in defining
rough selection outlines.
This lesson will teach you how to
use the Magic Wand tool to select a
consistently colored area, and then
how to reverse the selection outline
to select the areas that were
initially not selected. |
|
|
|
Step #1: |
|
|
·
Open a file that has a consistently
colored area, such as a blue sky. |
 |
|
|
|
Step #2: |
|
|
From the “Toolbox”:
·
Look for “Selection tools”.
·
Select the [ Magic Wand ]
tool. |
 |
|
|
|
Step #3: |
|
|
In the “Options bar”:
·
Choose [ New selection ] from
“Selection options”.
·
Enter 32 in the text box labeled
“Tolerance”.
·
Check [ Anti-alias ].
·
Check [ Contiguous ]. |
 |
|
|
|
Step #4: |
|
|
·
Position the pointer over the blue
sky and click inside the boundaries.
The Magic Wand tool will recognize
the color and select colors that are
similar to it. |
 |
|
Half of the blue sky is selected. |
 |
|
|
|
Step #5: |
|
|
In the “Options bar”:
·
Choose [Add to selection] in
“Selection options”. |
 |
|
|
|
Step #6: |
|
|
·
Click once in the blue areas that
were not selected.
·
Continue to click in each blue area
that was not selected, until all the
blue sky is selected.
Since you chose the Contiguous
option earlier, the selection is
limited to neighboring pixels only. |
 |
|
The blue sky is completely selected. |
 |
|
|
|
Step #7: |
|
|
·
Go to the “Menu bar”.
·
Choose Select > Inverse. |
 |
|
Now the selection is reversed. The
area under the blue sky is now
selected and can be edited.
The blue sky is no longer selected
and cannot be edited. |
 |
|
|
|
Step #8: |
|
|
·
Go to the “Menu bar”.
·
Choose Image > Adjustments >
Desaturate. |
 |
|
|
|
Step #9: |
|
|
·
Go to the “Menu bar”.
·
Choose Select > Deselect. |
 |
|
The area under the sky now looks
like different shades of gray. |
