Magic Wand and Quick Selections
Photoshop CS6 Tutorial
How to Make a Selection with the Magic Wand or Quick Selection Tool in Photoshop
At first glance the Magic Wand and Quick Selection tool appear to work the same way. The main difference is that the Magic Wand selects based on color and the Quick Selection tool looks for edges.
Open an image in Photoshop (File > Open).
Click the Magic Wand tool and set the Tolerance to 32 in the Tool options bar.
Click once inside an area that you wish to select. Depending on the range of color you may need to increase the Tolerance value to select more color or decrease the Tolerance value to make the tool less sensitive.
To add to a selection with the Magic Wand tool, press the Shift key and click to add to the selection.
To subtract from a selection with the Magic Wand tool, press the Option (PC - Alt), then click to subtract from the selection.
Now click the Quick Selection tool and click-drag across an object in the image. The tool looks for the object's edges and creates a selection.
With the Tool options set to Add to Selection, you can continue to click-drag to expand the selected area.
Set the Tool options to Subtract from Selection to remove portions of the selection.
