SECTION 3
Lesson 3.1: Making Selections

   

 

 

In this exercise, you will practice making selections with the Elliptical Marquee tool, the Polygonal Lasso tool, and the Magic Wand tool.

 

1.

First, start Photoshop CS by clicking the PhotoShop CS Icon on the desk top. You can also start Photoshop by choosing Start->Programs->Adobe Photoshop CS from the Windows start menu.

 

 

2.

After you start Photoshop CS, open the file named Old Image.jpg in the Photoshop CS samples folder. When you open the file you may see the following alert.

 

Just click the OK button to continue. Your Photoshop screen should look like something like the following:

 

 

 

 

3.

To begin, select the elliptical marquee tool from the Photoshop toolbox.

 

The elliptical marquee tool has a dashed circle icon and can be found in the upper left of the toolbox.

 

 After you select the tool, place your mouse pointer a couple of centimetres to the left of the person’s head, and drag a narrow ellipse vertically down the image for a couple inches. Without lifting your mouse button, drag horizontally to the right to expand the narrow ellipse into a circle around the person’s head.

 

Your selection should look something like this.

 

 

Put your mouse pointer inside the selection and drag the selection so it is centered over the person’s head.

 

 

4.

After you position your selection, right click on the image and click the Fill option in the menu that appears.

 

 

In the resulting dialog box, make sure that Foreground Colour is selected in the drop list at the top of the box, and enter 44 in the field labelled Opacity. Your image should now look something like the following:

 

 

In the History palette, right click on the history item labelled Elliptical Marquee, just beneath the Open history item.

 

Choose Delete from the pop up menu to clear all the changes you made to the image after opening it.

 

 

5.

Next, choose the Polygonal Lasso from the tool box.

 

You use the polygonal lasso by clicking the image to create a series of points. Photoshop will join the points with straight lines as you create them.

 

 

6.

 

Click the image at one of the corners of the neck tie, and then click on the next corner of the neck tie moving clock wise. Click all corners of the necktie in this way until you end up at your starting point.

 

When you are finished you should see an animated selection border around the neck tie.

 

 

7.

Right click on the image and choose Fill from the menu. Adjust the fill dialog just as before, but this time set the opacity value to 100.

 

 

 

Click the OK button in the dialog box to fill the tie with the foreground colour. Your image should now look like this.

 

 

Right click the Polygonal Lasso item in the history palette (underneath the open item), and select Delete from the pop up menu to delete the changes you have made to the image.

 

 

8.

Next, select the Magic Wand Tool from the tool box. (The icon looks like a magic wand).

 

In the options bar, enter 40 into the tolerance box and make sure there is a check mark in the contiguous (meaning adjacent pixels) check box.

 

Now click on the person’s upper shoulder on the right of the image. This should result in a selection that looks like this:

 

 

 

 

9.

Now, right click on the Magic Wand item just below the open item in the history palette list. In the pop up menu, click Delete. This should clear any changes that you made to the image.

 

 

10.

 Press Ctrl + Q to exit Photoshop CS. If you see the following alert, click the No button to leave the original image unchanged.
