Operation Manual

To turn on the automatic noise-compensation adjustment
1 Select a RAW image imported with or reprocessed using Aperture 3 image processing.
Note: If the RAW Fine Tuning controls do not appear in the Adjustments inspector or the
Adjustments pane of the Inspector HUD, the selected image is from a previous version
of Aperture. You must first reprocess the image using Aperture 3 image processing. For
more information, see Reprocessing Images from Previous Versions of Aperture.
2 In the RAW Fine Tuning area of the Adjustments inspector or the Adjustments pane of
the Inspector HUD, select the Auto Noise Compensation checkbox.
Aperture applies the automatic noise-compensation adjustment during the RAW decoding
process.
Working with DNG Files
In Aperture, you can adjust how the Mac OS decodes RAW images in the DNG format. If
the digital camera that captured an image is supported by Aperture, the calibration data
for that camera is used to decode the RAW file in the same manner as if it were decoded
from the RAW file format itself. If the DNG file is from an unsupported camera, Aperture
uses the camera information stored in the DNG file to decode the image.
To adjust the RAW Fine Tuning parameters of a DNG file
1 Select a DNG file imported with or reprocessed using Aperture 3 image processing.
Note: If the RAW Fine Tuning controls do not appear in the Adjustments inspector or the
Adjustments pane of the Inspector HUD, the selected image is from a previous version
of Aperture. You must first reprocess the image using Aperture 3 image processing. For
more information, see Reprocessing Images from Previous Versions of Aperture.
2 Adjust the RAW Fine Tuning parameters as necessary for the image.
Setting the Camera Default
When you’ve modified the RAW decoding settings using the controls in the RAW Fine
Tuning area of the Adjustments inspector or the Adjustments pane of the Inspector HUD,
you can save these settings as the default parameter values for the camera model. All
RAW image files from this camera model that are imported into Aperture are decoded
using these saved settings.
The camera model is
displayed in the Camera field.
