Choosing An Aperture Raw Converter
Aperture 1.1 actually contains two raw converters. There's the original 1.0 converter, which suffered from some
Rather than simply replacing the old converter with the new, Apple includes both converters in Aperture and allows you to
When you select a raw image in the Browser pane, Aperture automatically displays a small pop-up menu at the top of the Adjustments panel ( Figure 6.6 ). From this menu, you can select the converter that you want to use, and you can freely switch back and forth. After you select a new converter, Aperture will immediately reprocess your image and display the new conversion.
Figure 6.6. The raw converter pop-up menu lets you choose whether you want your raw images converted using the version 1.0 converter or the 1.1 converter.
If you select File > Migrate Images, you can specify global raw conversion rules that automatically convert your images to the 1.1 raw converter ( Figure 6.7 ).
Figure 6.7. The Migrate Images dialog box lets you specify which raw converter Aperture should use by default.
Fine-Tuning a Raw Image
When you select the 1.1 converter, Aperture adds a Raw Fine Tuning brick to the Adjustments panel ( Figure 6.8 ). This adjustment gives you a little additional manual control over the conversion of the current image.
Figure 6.8. When you choose to use the 1.1 converter, Aperture provides a set of Raw Fine Tuning adjustments.
Within Raw Fine Tuning, you'll find the following parameters.
: When Aperture applies its gamma correction curve, some of your image's tones are pushed deeper into the shadows, while others are
By default, the Boost slider is set to 1.0, meaning that the gamma correction curve is being applied at full strength. If you move the Boost slider all the way to the left, there will be no gamma correction curve applied at all, and you'll be viewing a linear image. The values in between let you apply more or less gamma correction.
If your images are slightly too contrasty, try moving the Boost slider to a lower value before performing other edits.
: Raw Fine Tuning provides a set of sharpening controls that work very much like the normal Aperture sharpening adjustment. The Intensity slider lets you specify how much sharpening to apply, while the Edges slider lets you independently sharpen edges. Sharpening here is a subtle control
Auto Noise Compensation
: This parameter
By default, these settings are initially configured with settings that Apple has deemed best for the type of camera that you're using. The Raw Fine Tuning adjustment identifies the type of camera that was used to take the image and loads settings from a prebuilt profile.
If you find that a different configuration of noise reduction and sharpening parameters works better, then you can save your new settings in a profile by choosing Save as Camera Default from the Settings pop-up menu in the Raw Fine Tuning brick ( Figure 6.9 ). Now any image you edit that was shot with that type of camera will receive these fine-tuning settings. In this way, you can easily define a custom raw conversion profile for your camera. You can switch back to the default conversion parameters at any time by choosing Apple from the Settings pop-up menu.
Figure 6.9. After defining raw tuning settings, you can save those parameters as the defaults for your camera.
Some raw converters embed their conversion parameters directly in the raw file. Files that have been modified in this way may not work with Aperture. Either switch to a pristine copy of the raw file or process it in the other converter and then import the results into Aperture.
