There’s nothing wrong with a little vanity. After all, sometimes a perfectly good portrait is marred by small yet annoying stuff like a zit, makeup smudge, or a stray hairs. 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. Happily, the Retouch tool in Photos for OS X can come to your rescue (it’s not available in Photos for iOS). As you’re about to learn, Photos’ Retouch tool is more powerful than the one in iPhoto.
How to use the Retouch tool
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. 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. Use the Zoom slider at the upper-left to zoom into the image and, if necessary, drag while holding down the spacebar to reposition the image so you can see the thing you’re about to remove.
