Operation Manual

• Click the left or right arrow in the Hue Boost value slider to adjust the accuracy of the
hues by 5 percent increments, or drag in the value field.
• Double-click the number in the Hue Boost value slider, then enter a value from 0.00 to
1.00 and press Return.
Use the Hue Boost slider and value
slider to protect hue fidelity during
the RAW decoding process.
A value of 0.00 preserves the original hues in the image in relation to the Boost adjustment
(color contrast) during the RAW decoding process. A value greater than 0.00 increases
the hue adjustment to the image. A value of 1.00 applies the full Apple-recommended
hue adjustment for the specific camera model.
Using the Sharpening Controls
You can adjust sharpening during the RAW decoding process by using the RAW Fine
Tuning Sharpening controls in the Adjustments inspector or the Adjustments pane of
the Inspector HUD.
Note: The effect of sharpening an image or group of images using the RAW Fine Tuning
adjustment is very subtle. More sharpening effects can be obtained using the Edge
Sharpen adjustment. For more information about the Edge Sharpen adjustment, see
Working with the Edge Sharpen Controls.
To adjust the sharpening applied during the RAW decoding process
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 Adjust the strength of the sharpening effect by doing one of the following:
• The default value for the Sharpening slider and value slider is determined by the camera
used to create the RAW image file. Drag the Sharpening slider to the right to increase
the strength of the sharpening effect applied during the RAW decoding process, and
drag the Sharpening slider back to the left to reduce the sharpening effect.
• Click the left or right arrow in the Sharpening value slider to adjust the strength of the
sharpening effect by 5 percent increments, or drag in the value field.
