Understanding Image Adjustments in Aperture
While Aperture has numerous functions dealing with importing and publishing your photos, it also has a powerful image adjustment engine that allows you to edit and manipulate your photos in any way you desire. It's a comprehensive facet of the program and contains many options and tools that can take quite awhile to familiarize yourself with. Once you get a handle on the basic functions, however, learning the rest shouldn't be too difficult.
Aperture uses a vast amount of tools, but it keeps them all arranged in a simple to use, intuitive interface. The brush tools, for instance, utilize slider bars to determine size, strength, effects and more. You can also hold down the shift key as you move the slider bars when altering an entire photo to see past the adjustments HUD. It also makes use of nondestructive brushes, which allows you to edit your photos using brushes that act in a less abrasive fashion. The Detect Edges option makes this even easier as it identifies edges in a photo and keeps the brush effects inside them.
Once you've completed the alterations to a specific photo, Aperture has the capability to spread those edits to a batch of photos, saving you the trouble of doing them all individually. You can use this option whether you use a preset adjustment or custom edits you've done yourself. Many adjustments, such as Exposure and Levels, have auto buttons which automatically apply preset edits to common problems. You can also select different adjustments to apply to different layers of a batch of photos, rather than having a single one laid out on the entire picture.
Aperture has many more options available; keep exploring, and you'll find there really is no limit to what you can do with your photo projects.
