Photoshop Tools:

The Magic Wand tool lets you select a area by color range without having to trace its outline. You can specify the color range, or tolerance, for the Magic Wand tool’s selection at tool’s option bar. Enter a low value to select the few colors very similar to the pixel you click, or enter a higher value to select a broader range of colors. To use Magic Wand tool, in the image, click the color you want to select.

Note: You cannot use the Magic Wand tool on an image in Bitmap mode.

Magic Wand Tool Options

Selection Mode (A): You can use the marquee tools to add to or subtract from existing pixel selections.

Note: Before manually adding to or subtracting from a selection, set the feather(b) and anti-aliased(c) values in the options bar to the same settings used for the original selection.

• Normal: Create New Selection. Your Current selection will be replace.
• Add: Add new selection area to current selection.
  
  
  
• Subtract: Remove new selection area to current selection.
  
  
  
• Intersected: Result in overlap area of your current selection and your new selection area.
  
  
  

Tolerance (B): Control range of color to be select. enter a value in pixels, ranging from 0 to 255. Enter a low value to select the few colors very similar to the pixel you click, or enter a higher value to select a broader range of colors.

Anti-Aliased(C): Smooth the jagged edges of a selection by softening the color transition between edge pixels and background pixels. Since only the edge pixels change, no detail is lost. Anti-aliasing is useful when cutting, copying, and pasting selections to create composite images. Turning off this option produces a hard-edged transition between pixels–and therefore the appearance of jagged edges.

Contiguous (D): To select only areas using the same colors connected. If unchecked all pixels in the image using the same colors will be selected.

Use All Layers (E): To select colors using data from all the visible layers. If unchecked the Magic Wand tool selects colors from the active layer only.
