Cropping and Histograms
Here’s a cool trick with the Crop tool. When you’re in the Develop module, you’ll always see that there’s the Histogram panel at the top right side of the Lightroom window. Well, the histogram always changes as you make adjustments to your photos. But, did you know that if you crop your photo with the Crop Tool (press R as a shortcut to get to it) that the histogram will update as you make adjustments to the crop area? Give it a try. As you move your crop area you’ll see the histogram continually update to reflect only the photo inside the crop.
