| 3. | The Boost slider lets you control the degree to which a default adjustment is applied to your image. By default, the Boost slider is set at full strength: your image appears with the full level of correction. As you drag the slider to the left, the correction is reduced. The Boost slider is handy for times when you feel your images are a little too contrasty or a little too saturated. |
| 4. | Aperture provides a built-in "round-trip" facility for importing and exporting images to another image-editing program. This capability is useful when you need to mask or composite images, selectively apply edits, or apply brush-driven retouching operations. To seamlessly work with another imaging application, such as Photoshop, you specify that external editor in Aperture's Preferences. Then, with the image you need to edit selected in the Browser, choose Images > Open With External Editor, or press Command-Shift-O. Make your edits in the other application, save the file, and switch back to Aperture. A new version of the image appears in the project, showing all of the edits that you just made. |
