Don't you just love Adobe Lightroom? It's neat and simple: no need to worry about layers and all that jazz (If that's not your kinda thing). It contains most of the tools you'll need to really polish a good photograph and improve it.
Adobe Lightroom, more than anything, is really designed to help you batch process images quickly and If you ask me it does it very well, but if you're just looking at a small selection of images it can still be tempting to sometimes whizz through them and rely 100% on the sliders. Again, if that's your style that's fine. But Adobe Lightroom is more than just sliders and batch-processing...
Adobe Lightroom's brush tools are effective! Please don't forget about them. There are often occasions where you don't want to apply a change to the entire photograph through a slider: for example clarity, sharpness or even exposure. But, at the same time taking that photograph over to Photoshop can feel like a real chore, so this is where Lightroom's brush tool is your friend: selectively lighten the eyes, selectively brush some clarity onto a face or even just brush a little vignette to two of the corners, instead of all 4. The brush tool unlocks a whole set of other possibilities for post processing to compliment the use of sliders.
In this video I talk about how I use brushes to further enhance a photograph that you wouldn't otherwise be able to do with sliders alone. I show you how to go from this, to this:
Please note that I know that brushes may not be to everyone's liking and the brush work demonstrated in this video is rough and fast, but for those who don't have Photoshop or prefer to stay within Lightroom - this may be just the thing you need to take your editing to the next level.
