The Previews preferences pane lets you adjust how Aperture creates
its photo previews.
Use embedded JPEG from camera when possible.
We recommend selecting this
option so that rather than having to open your RAW file and generate a preview (which
takes processing time), Aperture uses the camera-created JPEG that some cameras auto-
matically create when you take the photo.
Share previews with iLife and iWork.
Use this pop-up menu to choose when Aperture
updates its data file that contains information about your previews. Because we leave
Aperture running most of the time, we leave this set to Always. Leaving it set to Always
(rather than When quitting Aperture or Never) also makes it so we never wonder why
other iApps aren't seeing our latest previews.
Photo Preview.
This pop-up menu controls the dimensions for your previews. We leave
these set to monitor resolution so that full-screen slide shows look good using previews
rather than the original files. Preview JPEGs are easier for computers to open and process
instead of the full RAW files.
Photo Preview quality.
Use this slider to adjust the JPEG compression setting in your
previews. A higher quality means less compression. We find a value around 8 to be a
good balance between quality and disk size.
To turn off automatic preview generation for an existing project, select the project in
the Library Inspector and deselect Maintain Previews for Project from the Library
Inspector Action pop-up menu.
