The Magic Wand Tool:
This tool is handy when you have a solid color or similar colors in an area you want to select—say you had a solid yellow wall and you wanted to select it
so you could change its color. The Magic Wand tool will usually select that entire wall in just one or two clicks. Here, we want to select the sky, so get the
Magic Wand tool (it’s nested beneath the Quick Selection tool; or press Shift-W) and click it once in the sky. It selects some of the sky, but not all of it, so
press-and-hold the Shift key (to add to your selection) and click it again over any areas it missed—you might have to do this a few times. Also, the
Tolerance amount (up in the Options Bar) determines how many colors out it selects—the higher the number, the more colors it includes. So, if it selects
way too much, just enter in a lower number (the default number is 32. I usually try 20, and then 10, if it’s selecting too much, but in this case, it’s not
selecting enough. So, you can either increase the number a lot, or keep Shift-clicking over areas that didn’t get selected, which is usually what I do). I went
ahead and desaturated the sky here—not what I would actually do, but I wanted you to clearly see we were fully able to select the sky. Okay, now you
should have a handle on the essential selection tools.
