Modifying Settings Applied to the Entire Slideshow
An Overview of Modifying the Entire Slideshow
The onscreen duration of each slide, the type of transition between slides, and the length of the
transitions are initially set by the theme you choose for the slideshow. However, you can change
these settings at any time, along with the aspect ratio, background color, image borders, Ken
Burns eect settings, and titles. For more information about working with slideshow themes, see
Changing a Slideshow’s Theme on page 461.
Setting the Aspect Ratio for the Slideshow
Determining the aspect ratio of the slideshow is the rst setting you need to address. Aperture
slideshows can be output at aspect ratios that match either the main or secondary display, the
dimensions of a standard 4:3 or 16:9 widescreen TV, or the 3:2 aspect ratio of iPhone.
To set the aspect ratio for the slideshow
m If the Default Settings pane of the Slideshow Editor is not shown, click the Default Settings
button, then choose an aspect ratio from the Aspect Ratio pop-up menu.
Looping the Slideshow and the Main Audio Track
You can set the slideshow to play repeatedly in full-screen mode until you stop playback by
pressing Esc. You can set playback of the audio clip in the slideshows main audio track to loop
until the end of the slideshow.
To set the slideshow to loop in full-screen mode until stopped
m In the Default Settings pane of the Slideshow Editor, select the “Repeat slideshow” checkbox.
To loop playback of the slideshow’s main audio track
m In the Default Settings pane of the Slideshow Editor, select the “Loop main audio track” checkbox.
Applying a Title to the Slideshow
You can apply a title to the beginning of your slideshow. You can also display your title over a
solid background by inserting a blank slide.
Note: The title controls in the Selected Slides pane of the Slideshow Editor and the title options
in the Slideshow Action pop-up menu (with a gear icon) are available for use only with the
Classic and Ken Burns slideshow themes. If iPhoto ’11 is installed, a new Text control appears,
allowing you to add text to any slideshow theme.
