Adobe Photoshop CS2 CLASSROOM IN A BOOK [Electronic resources] نسخه متنی

Once you've made a selection, what area of the image can be edited?

How do you add to and subtract from a selection?

How can you move a selection while you're drawing it?

When drawing a selection with the Lasso tool, how should you finish drawing the selection to ensure that it is the shape you want?

How does the Magic Wand tool determine which areas of an image to select? What is tolerance, and how does it affect a selection?

Only the area within the selection can be edited.

To add to a selection, hold down Shift and then drag or click the active selection tool on the area you want to add to the selection. To subtract from a selection, hold down Alt (Windows) or Option (Mac OS) and drag or click the active selection tool on the area you want to remove from the selection.

Without releasing the mouse button, hold down the spacebar and drag to reposition the selection.

To make sure that the selection is the shape you want, end the selection by dragging across the starting point of the selection. If you start and stop the selection at different points, Photoshop draws a straight line between the start point of the selection and the end point of the selection.

The Magic Wand tool selects adjacent pixels based on their similarity in color. The Tolerance setting determines how many color tones the Magic Wand tool will select. The higher the tolerance setting, the more tones the Magic Wand selects.
