- [Instructor] You may have captured a series of frames
that are essentially the same,
like this group of photos that we see here.
I'm viewing the Chapter 5 05_01 folder.
If you shoot in the high speed capture mode,
or if you shoot frames for HDR photography,
you'll want to group the similar frames into stacks
because folders with similar images can be really large,
and stacking the similar photos into groups
makes it easier and quicker to navigate.
Let's take a look at how we can do this.
In order to group the photos into a stack,
we have to first select them.
So I have the first image selected, the first butterfly.
I'll hold the Shift key down and select the last one,
and then go up to Photo, and come down to Stacking,
and we see Group into Stack.
The keyboard shortcut is Command + G for a Mac,
and Control + G for Windows.
And now we only see a single butterfly in our grid.
And also down here in the film strip,
let's make this a little bigger so we can see it.
In the film strip it shows us in the upper left-hand corner
that there are 24 images gripped into this stack.
If I click on the 24, it will open up that stack.
It didn't unstack them.
They're still grouped,
but we can look at the individual images this way.
We can collapse that back down
by clicking in the upper left-hand corner.
We can do this as well from the grid view,
but it's a little harder to see.
Let's make the thumbnails bigger.
If you look really close,
this thumbnail has a handle on the right side
and the left side, and clicking on the right edge of that
will open up that stack
so that we can see the individual images.
And clicking on the left side of the frame
will collapse it back down.
We can rearrange the order of the images in here as well.
If I open this up and just drag and drop
that'll change the order.
Maybe I want to put a different image
on the top of the stack
so that when I'm searching through my folder,
I'll see a different frame.
This one has the butterfly wing cropped off,
so let's take this image here where it's not cropped off
and drag it to the first position,
and then collapse this stack back down,
And we'll see that that frame is now the top of the stack.
Let's make the thumbnails a little bit smaller
and I'll show you how easy it is
to remove a photo from the stack.
So I'll open this back up.
Let's make this even smaller.
And then I can take any one of these frames,
and just drag and drop it out.
To unstack or ungroup,
we can come back up here to Photo, Stacking, Unstack,
which is the Shift + Command + G, or Shift + Control + G.
Now we're back to where we started
with none of the images stacked.
I want to show you an auto way to do this,
which is even faster.
If we come up here to Photo,
and then go back down to Stacking again,
there's an option to Auto Stack by Capture Time.
And it's finding four different groups of images,
which is exactly what I have.
And it didn't matter that that one image
I had dragged to a different location,
because it's using the capture time of the frames.
So I'll go ahead and click that to stack all four of those.
Notice how much cleaner this looks now.
As you can see, stacks are really useful
for keeping multiple similar photos in one place,
reducing clutter in the grid view, and in the film strip.
