Change the number of photos in the Viewer
You can specify whether the Viewer displays one photo, three photos, or multiple photos at a
time. If your system uses multiple displays, you can configure your main and secondary displays
to show single photos, three photos, or multiple photos simultaneously. The display settings you
choose also control the display of photos in full-screen view.
Change the number of photos displayed in the Viewer
m To display multiple photos: Choose View > Main Viewer > Show Multiple (or press Option-U).
This is the default setting. When Show Multiple is chosen, the Viewer can display anywhere from
one photo up to twelve at a time, depending on the number of photos selected in the Browser.
m To display a single photo: Choose View > Main Viewer > Show One (or press Option-R).
When the Viewer is set to Show One, the Viewer displays one photo at a time regardless of the
number of photos selected in the Browser. This setting allows you to make a multiple photo
selection in the Browser and then view each photo by itself within the selection.
m To display three photos: Choose View > Main Viewer > Three Up (or press Option-H).
When the Viewer is set to show three photos at a time, Aperture displays the selected photo in
the center of the three photos that appear in the Viewer.
Compare photos
You can select a photo against which to compare other photos in your project or in the library.
The selected photo remains on the screen as you select and display other photos (alternates)
to compare against it. The comparison feature is useful for making final selections of the best
photos in a series or comparing two versions of a photo for correct exposure or highlights.
When comparing photos, you can apply ratings and keywords and make adjustments to
selected photos.
