Draining Color

You’ve probably heard the saying, “You get what you pay for.” In Photoshop, that saying translates to, “The quickest method ain’t always the best!” In other words, some techniques take a little extra time, and converting a color image to black and white is one of ’em—but it’s well worth the effort.

To drive that point home, open a colorful image—if you want to follow along, you can download Dragon.jpg from this book’s Missing CD page at www.missingmanuals.com/cds—and then choose Image→Adjustments→Desaturate.

Photoshop keeps the currently active channel, tosses the rest, and you’re left with a black-and-white image…that nobody is going to write home about. As you’re about to find out, Photoshop has several ways to produce beautiful black-and-white conversions, not including the two methods mentioned above.

Cruise on over to this book’s Missing CD page at www.missingmanuals.com/cds to learn how.
