To use it, select an image in Photos and then press Return to enter Edit mode, or press the Edit button in the upper-right of the toolbar. The Retouch tool works by copying pixels from one area of your photo to another and then blending them (blurring, really) into the pixels you click or drag atop.
As you’re about to learn, Photos’ Retouch tool is more powerful than the one in iPhoto. Happily, the Retouch tool in Photos for OS X can come to your rescue (it’s not available in Photos for iOS). Or maybe you captured an object in the frame you wish you hadn’t, or you scanned the image and introduced dust specks, or perhaps your camera’s sensor is a little dirty.
After all, sometimes a perfectly good portrait is marred by small yet annoying stuff like a zit, makeup smudge, or a stray hairs. There’s nothing wrong with a little vanity.
