If you use the auto-stack feature, Lightroom might stack some photos together that don’t actually belong together. If that happens, it’s easy to split a stack and have those other photos separated into their own stack. This is where I use splitting the most (for auto-stack mistakes), but you can use it any time you want to separate some of the photos in a stack for any reason. To split a stack, just select the photos you want to split out, Control-click (PC: right-click) any of those selected photos, and choose Stacking > Split Stack. Now you’ll have two stacks. In the example in Figure 11, I split the original stack of 12 into one stack with nine photos, and one with three photos.
