Now look on your Desktop. You’ll see a large arrow icon, pointing to the name of the droplet (see Figure 7). Here’s what a droplet does: If you drag-and-drop a photo that’s on your Desktop, or in a folder on your computer, right onto this droplet (a JPEG, TIFF, PSD, etc.), the droplet automatically launches Photoshop, opens that photo, and applies the Luminosity Sharpening action to that photo you dropped. Then it saves and closes that sharpened photo automatically (because you recorded saving and closing as part of the action). You also can create batch actions, so that you can drag-and-drop an entire folder of photos onto the droplet and it will process each one automatically. Cool stuff.
