Adjust how Aperture decodes RAW images
RAW Fine Tuning controls overview
You can modify how OS X decodes RAW files 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 file format for each digital camera supported by Aperture. This calibration
data usually results in the optimal decoding of the RAW image files for a particular camera.
However, certain types of images may require adjustments to how OS X decodes the RAW
image file.
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 fine-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 effect found in images with subjects whose linear
patterns introduce the effect, 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 file format. Some camera models can create
multiple types of RAW file formats, and different controls may be available for each of these RAW
file formats.
Using these controls, you can fine-tune your RAW decoding settings on an image-by-image basis.
Aperture also enables you to save your customized RAW decoding settings as effects or as the
default settings always used with a specific 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 first 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.
