Using the Auto Exposure Button
When you want to quickly adjust the exposure of a RAW image, you can use the
Auto Exposure button. Depending on the exposure Aperture sets for the image, you
can always fine-tune the image’s exposure setting using the Exposure controls. For
more information about manually adjusting the exposure of an image, see “
Working
with the Exposure Controls ” on page 412.
Note: Automatic exposure adjustment is available for Aperture-supported RAW images
only. If you want to adjust the exposure of another file type, such as JPEG or TIFF, see
“
Working with the Exposure Controls ” on page 412. For a list of supported RAW file
types, go to the Apple website at http://www.apple.com/aperture/raw .
