The magic wand tool allows you to select areas of similar color and brightness value based on the pixel that you click on. This is the magic wand tool in the tool palette. And notice when you click and select the magic wand tool that we have some various options available to us for this particular tool. Perhaps the most important one is the tolerance setting. The tolerance setting value is a range of similar colored pixels that will be included in your selection. The lower this number, the less similar pixels are included in your selection. And the higher the number, the more pixels are included in your selection. So with the value of 32, it's a good starting point, we can go ahead and click anywhere to select the sky and you can see that it's done a pretty good job, but I need to go ahead and select these lighter areas that were not included. So I'll hold down the shift key, which will allow me to add to my selection. Also notice that my magic wand tool was contiguous in nature, because this check box has been enabled to the word contiguous. So what that means is that my selection will stop at any area that has a dramatic change in color. And to demonstrate that, I will disable contiguous and click on this body of water here. Notice that it's selecting pixels of similar color throughout my entire document - up here in the trees and over here as well. I'll deselect that and enable contiguous, and then click in this body of water and you can see that my selection is now contained just to where the pixels have the basic same color, and there was a tremendous difference in color around this area. So that's the difference between contiguous and non-contiguous use of the magic wand tool. I'll go ahead and deselect that. And show you how you can use the magic wand tool to do something such as select these trees in the hills here. I'm going to turn the value down of my tolerance to about 24, and click once in my trees. And since my selection was contiguous in nature, you can see that it's not selecting trees past these other color ranges here. So I'm going to go ahead and add them to my selection by holding down the shift key, and clicking on some of these other tree clumps. And if you are getting some trees that you don't really want in your selection, you can always switch to something like the lasso tool. And I'm going to hold down the option key, which will allow me to deselect whatever area I enclose in my freehand lasso selection. So there are my selected trees, using the magic wand tool. I could do something fun such as increase the contrast for these trees. I'm going to go ahead and hide the edges, command + 'H', and bring up my levels, and popup the contrast for my trees. So there are my more contrasty trees after running levels, and this is what it looked like before levels.
