"BRANDON SARKIS: My name is Brandon Sarkis on behalf of Expert Village. Today, I'm going to be showing you how to use Adobe's Lightroom software. I'm going to go over the Stacks Feature. So what we're going to do is we're going to scroll up to the top menu bar right up here. Well, it's actually--let's go to different imports so we can actually see some stacks in action. You'll see here that, you'll see a couple of stacks pop up already. This is from an old import I've got with multiple exposure images, which is why I like to use stacks because I take multiple exposures and make HDRs of them. So let's scroll down here to our stacking and you can see some options "Unstack," "Remove Some Stacks," "Split Stack," "Expand," "Collapse All," "Expand All," "Move the Stack," "Move Up," "Move Down" and "Auto-Stack By Captured Time." The reason you want to move them up and down is to put your representative photo on top so you can recognize the stack easier 'cause the one that automatically stacks on top may not be the one you want to see. And you can also do "Auto-Stack by Captured Time" which is really nice. In the event you're doing multiple exposure settings or really fast captures, this way you can have it automatically, stack them together. So that way, you can have all your same photos grouped together. So we're just going to click here on this and you see it expands it out. This is one of two--one of three, two of three, three of three, which is nice. I'm going to click here on this one. And they're more of the same. You can scroll down like--let's actually make a stack so you would think you would just click and drag one together like this, but you can see, that doesn't work. So what you're going to want to do is you're going to select both of those, and you're going to go up to--just unselect that one. Then, we're going to go to our stacks, and we're going to hit "Group into stack" or you can also hit command G, or apple G, and give it a second. It's gotta think. Keep in mind it's dealing with, you know, 10 megabyte photo images. So there we go. There's our new stack, just like that."
