The adjustment brush has been greatly improved in Lightroom 5. We now have the ability to do most retouching in Lightroom and not have to round trip into Photoshop. You can retouch skin, lighten wrinkles, adjust eye color, make lips more glossy and more. Non destructive edits with sliders attached so, now you can go back and tweak to you hearts content.
Once you get an adjustment you like you can save the brush so, next time you need to a that adjustment just select the brush your created from the drop down menu and paint away. The adjustment brush is the key to retouching in Lightroom you can layer them similar to the way you can layer adjustment layers in Photoshop. Once you get a understanding of how it works you’ll be retouching in Lightroom and saving yourself time involved in a round trip to Photoshop and back on more retouching tasks. You can also buy brushes to give you a head start like the set from my friend Brett at lightroomretouching.com. I have Brett’s brushes and they give you a great starting place for skin, dodging and burning and may others there are 49 of them even brushes for adding makeup like lipstick or blush.
