Chapter 7 Make image adjustments 334
Adjust how Aperture decodes RAW images
RAW Fine Tuning controls overview
You can modify how OS X decodes RAW les using the adjustment controls in the RAW Fine
Tuning area of the Adjustments inspector or the Adjustments pane of the Inspector HUD. OS X
characterizes the RAW le format for each digital camera supported by Aperture. This calibration
data usually results in the optimal decoding of the RAW image les for a particular camera.
However, certain types of images may require adjustments to how OS X decodes the RAW
image le.
The RAW Fine Tuning controls include the following parameters:
•
Boost: Use the Boost and Hue Boost sliders and value sliders to control image contrast.
For more information, see Use the Boost controls on page 335.
•
Sharpening: Use the Sharpening and Edges sliders and value sliders to ne-tune the amount
of sharpening you want applied to images during the RAW decoding process.
For more information, see Use the Sharpening controls on page 335.
•
Moire: Use the Moire and Radius sliders and value sliders to correct color fringing in high-
contrast edges and the moire pattern eect found in images with subjects whose linear
patterns introduce the eect, such as a brick wall or a picket fence.
For more information, see Use the Moire controls on page 336.
Note: Some controls in the RAW Fine Tuning area of the Adjustments inspector and the
Adjustments pane of the Inspector HUD appear dimmed if these settings aren’t available for
use with images derived from a particular RAW le format. Some camera models can create
multiple types of RAW le formats, and dierent controls may be available for each of these RAW
le formats.
Using these controls, you can ne-tune your RAW decoding settings on an image-by-image basis.
Aperture also enables you to save your customized RAW decoding settings as eects or as the
default settings always used with a specic camera, so that you can easily apply them to newly
imported images. For more information, see Set the camera default on page 338.
If the RAW Fine Tuning controls don’t appear, the selected photo is from a previous version of
Aperture. You must rst reprocess the image using the most current RAW image processing. For
more information, see Reprocess photos from earlier versions of Aperture on page 49. If you do
not see the Reprocess button, the image may not be a RAW photo.
