Use the Saturation, Definition, and Vibrancy brushes to help draw
attention to your subject.
Use the Sharpen Quick Brush to apply a basic sharpening effect to localized areas
of the image.
We suggest you use this option sparingly because you have less control
over the sharpening parameters this way than if you use the Edge Sharpen adjustment.
Use the Halo Reduction Quick Brush to remove any halos such as purple fringing
that may occur with certain lenses.
The halo reduction is slightly different from the
Chromatic Aberration adjustment and is not necessary with most lenses. However, if you
check your image at an increased magnification of 100 percent or more and discover
purple fringing, this Quick Brush can be invaluable.
Use the Noise Reduction Quick Brush to remove noise from specific areas of the
image.
Creating and Using Adjustment
Presets
The new adjustment presets in Aperture 3 are major timesavers, as we've already mentioned with
the white balance presets. There are a series of presets that Apple includes by default, and addi-
tionally you can create your own presets that contain a combination of various adjustments. In
addition, you can add presets that you download from other sites. All presets can be applied to
your images as they're being imported, or you can apply them to one or more images as you edit
