This video discusses the non-destructive applications of both the adjustment brush and the graduated filter application in Adobe Photoshop Lightroom 2. These powerful tools will let you adjust exposure, brightness, contrast, saturation, clarity and sharpness - locally and non-destructively. No more going into Photoshop and using adjustment layers with masks. Instead, Lightroom 2.0 allows for instant masking! This feature alone, at least in my opinion, is more than worth the cost of Lightroom 2 (available from Amazon.com for $260!).
