A question I’m constantly asked is: “How can I set my favorite image adjustments as the defaults when I open the Heads Up Display?” For a while, I didn’t know the answer myself until I found this post by Jacob Lauemøller in the Aperture Discussion Forums. The answer is a simple edit to the AdjustmentDefaults.plist file.

The procedure is simple. Close Aperture. Go to your Home Folder > Library > Application Support > Aperture. Make a copy of the AdjustmentDefaults.plist file and stash it in a safe place. Open your original version in the Property List Editor or any good text editor such as TextWrangler.

The control that most people want to add as the default is Edge Sharpen. To do so, add a new sibling after the last string and type RKProSharpenOperation (in the Property List Editor), or if you’re using a text editor, just add a new string tag and type in RKProSharpenOperation after the last string in the list. You can refer to the examples below. The top example is using the Property List Editor and the bottom example is with a text editor.

Restart Aperture, find an image to edit, open the HUD, and you will see Edge Sharpen as part of the default list. Jacob lists other strings you can add too:

  • RKRedEyeOperation (Red Eye)
  • RKStraightenCropOperation (Straighten)
  • RKCropOperation (Crop)
  • RKDustRemovalOperation (Spot and Patch)
  • RKChannelMixerOperation (Monochrome Mixer)
  • RKNoiseReductionOperation (Noise Reduction)
  • RKSharpenOperation (Sharpen)

As with any other hack, back up your original data, proceed with care, and experiment at your own risk. (Have fun too!).
