Working with Stacks

The following sections describe the various options you have while working with stacks:

Opening and Closing Stacks

You can close a stack and open it again whenever you wish. You may want to do this to free up space in the Browser. You can also close stacks to quickly reduce the number of images you must sort through visually when selecting images for a final photo edit. When a stack is closed, only the stack’s pick image appears in the Browser.

To close a stack
Do one of the following:
  • Select an open stack, then choose Stacks > Close Stack (or press Shift-K).

  • Click the Stack button on the pick image.

    Figure. Closed stack showing the pick image that represents the stack.
To close all stacks
  • Choose Stacks > Close All Stacks, or press Option-Semicolon (;).

To open a stack
Do one of the following:
  • Select a closed stack, then choose Stacks > Open Stack (or press Shift-K).

  • Click the Stack button on the pick image.

To open all stacks
  • Choose Stacks > Open All Stacks, or press Option-Apostrophe (’).

Designating a Pick Image for a Stack

The pick image represents the stack. You can set the image you like best as the pick, or Aperture can set the pick automatically. When you select and stack images manually in the Browser, the leftmost image becomes the pick. You can change the pick whenever you wish.

To set an image as the pick
Do one of the following:
  • Select an image in the stack, then choose Stacks > Pick, or press Command-Backslash (\).

  • Drag the image you want into the pick (or leftmost) position in the stack. When you see a green bar appear, release the mouse button.

Designating an Album Pick for a Stack

The same stack may appear in several albums. Depending on the purpose of the album, you may want a different pick image for each album. For example, a stack in a webpage album may have one pick image, and the same stack in a book album may have a different pick image adjusted for printing. You can designate a specific image in a stack to be an “album pick”—the pick for the stack within a specific album. Each album can have a different album pick for the stack.

An album pick appears with the Album Pick badge.

To select an album pick for a stack that appears in multiple albums
  • Select an image in the stack, then choose Stacks > Set Album Pick, or press Command–Shift–Vertical Bar (|).

To clear an album pick for a stack
  • Choose Stacks > Clear Album Pick, or press Command–Shift–Vertical Bar (|) again to clear the album pick designation.

Arranging Images in a Stack

It can sometimes be difficult to decide which image in the stack should be the pick. In many cases, images are so similar that more than one merits the pick position. For this reason, you may want to have alternate images available when presenting images to clients.

You can change the order of images within a stack to help you choose the pick and alternates. Moving an image to the left promotes it; moving it to the right demotes it.

To promote an image in a stack
Do one of the following:
  • Select an image, then choose Stacks > Promote, or press Command–Left Bracket ([).

  • Drag the image over the image location you want until you see a green bar appear, then release the mouse button.

To demote an image in a stack
Do one of the following:
  • Select an image, then choose Stacks > Demote, or press Command–Right Bracket (]).

  • Drag the image over the image location you want until you see a green bar appear, then release the mouse button.

Adding Images to and Removing Images from Stacks

You can add images to and remove images from stacks at any time. You can drag images into or out of a stack, and you can also drag images from one stack to another.

To add an image to a stack
Do one of the following:
  • Select the images in a stack and the image you want to add to the stack, then choose Stacks > Stack (or press Command-K).

  • Drag the image into an expanded stack.

To remove an image from a stack
Do one of the following:
  • Select the image, then choose Stacks > Extract Item (or press Shift-Option-K).

  • Drag the image out of an expanded stack.

Splitting Stacks

You can split a stack into multiple stacks to refine the organization of your images. All images remain stacked, but they are now part of new stacks. The image selected as the splitting point becomes the pick for the new stack.

To split a stack
  1. In an expanded stack, select the image that you want as the first image in a new stack.

    Figure. Expanded stack containing four images, with one image selected.
  2. Choose Stacks > Split Stack (or press Option-K).

    Figure. Two expanded stacks created from the previous stack, with the selected image in the pick position for the new stack.

The selected image becomes the pick of the new stack.

Dragging Stacks

You can drag an entire stack to a new location, and you can drag specific images within a stack to a new location. When a stack is closed, dragging the stack moves the entire stack. When a stack is open, you can drag individual images to new locations in the Browser. You can also drag images into a stack. If you drag an image within a stack into a different project, however, the entire stack moves to the new location.

When you drag a stack into a webpage album, web journal album, book album, or slideshow album, the entire stack appears in the Browser, but only the stack picks can be used for publication in webpages, web journals, books, and slideshows.

Comparing Images in Stacks

To help with the photo editing process, you can set the Viewer and Browser to automatically open a selected stack and set up the stacked images for comparison. The pick of the stack is set as the “compare” image. This stack-viewing feature also works in Full Screen view.

To set the Viewer to automatically open and compare the images in stacks
  • Choose View > Main Viewer > Stack (or press Option-T).

    Figure. Viewer set to Stack mode showing a stack.

The compare image is surrounded in a green border, and the alternate image is surrounded in a white border.

Tip: When the Viewer is in Stack mode, you can press the Up Arrow and Down Arrow keys to move from stack to stack.

To select another alternate image
  • Press the Left Arrow and Right Arrow keys.

To select another stack
  • Press the Up Arrow and Down Arrow keys.

To promote the alternate image in the stack
  • Press Command–Left Bracket ([).

To demote the alternate image in the stack
  • Press Command–Right Bracket (]).

To set the alternate image as the stack pick image
  • Press Command–Backslash (\).

Working with Stacks in List View

If you prefer, you can create and work with stacks in list view. You can select images to stack, select a pick, add and remove images, and split stacks, just as you can in filmstrip view and grid view.

In list view, a stack is identified by a disclosure triangle beside the name of the pick image.

To open and close stacks in list view
  • Click the disclosure triangle beside the name of the pick image.

You can work with the images in a stack in list view by dragging, pressing keyboard shortcuts, or choosing commands from the Stacks menu.
