Operation Manual

Image Processing
Aperture provides a powerful set of nondestructive adjustment controls that allow you
to improve and enhance your images using adjustments such as Crop, Straighten,
Exposure, White Balance, Levels, Curves, Vignette, and more. In addition, Aperture lets
you apply or remove adjustments selectively, affecting only certain parts of an image, by
using brushed adjustments.
For especially efficient image adjusting, you can save adjustment settings as presets
(collections of saved settings) and apply a combination of image adjustments to one or
more images in a single step.
