Photoshop Lightroom, Part 2
Although Photoshop gets all the glory, in Photoshop Lightroom, Adobe has created a tool that will help professionals take control over their image libraries and catalogs of work
Healing/Cloning And Red-Eye
So far, all I've written about are “Global Image Adjustments,” meaning nothing is done to an image in a locally selected area. But Lightroom does offer its inaugural “local” image adjustment in the form of a Spot Healing/Cloning tool as well as a Red-Eye Reduction tool.
Located in the Toolbar, the user can select between either Clone or Heal as the logic. The function is a bit different than what's found in Photoshop. While the basic algorithms are related, the implementation is different because this is a metadata editor, remember? Rather than working directly in the pixels, these edits are stored as metadata that will only be applied upon processing.
The main design is to take care of sensor noise and obvious flaws in images. It's not intended to completely eliminate the need for Photoshop's powerful retouching tools. Generally, I use the Healing function rather than the Clone. Also, you'll often find that the spot that Lightroom “guesses” at selecting for a “source” may not be optimal.
For those cases, simply grab the Source of the Heal brush and drag it. With practice (it's different than Photoshop), one can become proficient rather quickly. And Lightroom's Healing has one major advantage over Photoshop's—users can apply spotting for an image and then Sync that spotting to as many images suffering from the spots. The spotting can't be stored into presets, but they can be applied to multiple images easily.
Here's the result of spending about eight to 10 minutes of spotting:
