Operation Manual

Creating Stacks
You can create stacks in two ways: you can specify that Aperture create stacks
automatically, or you can create stacks manually. For example, if you shoot a series of
images in quick succession (such as at a sports event) or if you bracket images to allow
for differences in lighting or exposure, you most likely will want to view those images
together. Aperture can stack those images based on metadata recorded by the camera
as the series of pictures is taken.
A series of images taken
in quick succession.
• Image series: With a series of images shot in quick succession, Aperture can determine
the images in a sequence and group them in a single stack. For example, sports
photographers shoot rapid bursts of images to capture actions. Based on timeline
metadata—when a series of shots was taken and the interval between shots—Aperture
can determine which images fall into a sequence and group them in stacks.
• Bracketed shots: These typically represent a series of three pictures with slightly different
exposure settings. Advanced digital cameras often have options for shooting bracketed
shots automatically. When Aperture detects a series of bracketed images, it includes
the neutral image and the over- and underexposed images in the stack.
For more information about creating stacks automatically, see Creating Stacks
Automatically.
For more information about creating stacks manually, see Creating Stacks Manually.
Creating Stacks Automatically
You can have Aperture automatically group related images into stacks.
To automatically stack images
1 In the Library inspector, select a project or an album that contains the images you want
to stack.
2 Choose Stacks > Auto-Stack (or press Command-Option-A).
