Fitting the Slides to the Aspect Ratio
After you have chosen an aspect ratio for your slideshow, you need to decide how you want
your photos to appear within the aspect ratio. Use the Crop pop-up menu in the Default Settings
pane of the Slideshow Editor to choose to have the photos t within the frame of the slideshow
aspect ratio, have the photos ll the frame of the slideshow aspect ratio, or apply a Ken Burns
eect to each photo in the slideshow. A Ken Burns eect either zooms in to or out of the photo
while simultaneously panning along the widest dimension of the photo.
You can have Aperture scale the photos so that they ll the screen, with no part of the
background showing. Keep in mind that Aperture must zoom in to most of the photos to make
them t the aspect ratio of the slideshow. This means that parts of the photos will be cropped.
To set the crop characteristics for your photos
m To t every photo in the slideshow within the chosen aspect ratio without cropping the photos:
Choose Fit in Frame from the Crop pop-up menu.
m To have every photo in the slideshow ll the frame of the chosen aspect ratio: Choose Fill Frame from
the Crop pop-up menu.
Cropping will occur along the longest dimension of each photo unless the photo’s aspect ratio
matches the aspect ratio chosen in the Aspect Ratio pop-up menu. Drag within the images to set
the portions of the photos that are visible.
m To apply a Ken Burns eect to the photos in the slideshow: Choose Ken Burns Eect from the Crop
pop-up menu.
