Adding to and subtracting from selections
You created a selection that surrounds the snowboarder. You'll now use the Lasso tool to
rei ne that selection.
Deleting from the selection
In this part of the exercise, you learn to subtract from your active selection.
1
Select the Lasso tool (
) in the Tools panel.
2
Look at your image and determine the areas of your selection that you want to delete.
This might include the area between the snowboarder and the selection of the sky
surrounding him.
3
Press and hold the Alt (Windows) or Option (Mac OS) key and notice that the cursor
turns into a Lasso with a minus sign. While holding the Alt/Option key, click and
drag outside the selected area and into the active selection. Release the mouse when
you have circled back to your original starting point. The new Lasso selection you
made is deleted from the existing selection.
4
To practice this skill, press and hold the Alt/Option key, and click to start your lasso
path on the edge of the snowboarder. Then, click and drag along the edge of the
snowboarder for a short bit. When you want to end the lasso path, make sure to circle
back around to the start point.
Carefully drag along the edge of the snowboarder, and then circle back to your starting
point, enclosing the section that you want to delete from the active selection.
You do not have to delete the sky from all the edges of the snowboarder for this
exercise. However, to prepare for the next section, you will delete the section between
the snowboarder's legs and the board.
