Apple Aperture 3.5 - Manual (Page 251)

Chapter 7 Make image adjustments 251
When you need to clone pixels from a different area of an image to fix the area where the
blemish is, you use the “patching” method. Patching is similar to spotting, except that there are
some additional steps. You first place a Spot & Patch target overlay (yellow) over the blemish, and
then you place a source target overlay (white) over the area you want to clone. The pixels in the
Spot & Patch target overlay are replaced by the pixels copied from the source target overlay.

For both spotting and patching, Aperture provides additional parameter controls to allow you to
adjust the softness, opacity, and amount of detail in the cloned pixels, so that the corrected area
looks as natural as possible.

1 Select a photo.
2 To display the photo at full size, click the Zoom Viewer button in the tool strip or the full-screen
view toolbar (or press Z).
Setting the photo to appear at full size (100 percent) prevents image scaling from
obscuring details.
3 Choose Spot & Patch from the Add Adjustment pop-up menu in the Adjustments inspector or
the Adjustments pane of the Inspector HUD.
The pointer changes to a target, and the Spot & Patch HUD appears.
