You’re probably thinking, "What’s a droplet?" I’ll explain that in the next step (it’s easier to explain then). For now, just follow along with me in the Create Droplet dialog box. At the top of the dialog box, click the Choose button, choose your Desktop as the destination for saving your droplet, and name this saved droplet "Unsharp Mask." In the Play section of the dialog box, choose Luminosity Sharpening (the named we gave our action earlier) from the Action pop-up menu (see Figure 6). You can ignore the rest of the dialog box, and just click OK.
