About Aperture Presets
With each zip file there is a detailed instruction PDF for how to add the preset to Aperture. If you want to skip the PDF you can just read the following instructions. Apple makes it super easy to just drag and drop the presets into Aperture.
Brief instructions:
Installing the effects:
Start by unzipping the file you downloaded. You’ll save it to your desktop or other location thats easy for you to find. Installing presets in Aperture is quite simple. You can select the presets file (the one file contains the whole set) and drag it onto Aperture in the Dock. The presets will appear in the “Presets” dropdown of the “Adjustments” tab. Alternately you can also import the presets from the edit presets menu (accessible from the “Presets” dropdown) and browse to the presets file to import.
Usage:
With a photo selected you can select the “Presets” menu and browse to the desired effects. Aperture will show a preview of what the effect will look like. Clicking the preset will apply it to the photo. You can select another preset and apply it over the top of the previous. Settings from the previous effect will be left alone unless the new preset defines a change in a given parameter. Alternately you can hold the “Option” key while you apply a preset and it will clear previous settings and only apply that preset.
