Apple Aperture 2 - Manual (Page 400)

400 Part III Performing Image Adjustments
You can use two different methods to straighten your images. You can use either the
Straighten tool or the Straighten adjustment controls. However, you may find it most
efficient to use the Straighten tool to quickly level the image so that it’s roughly
straight, and then use the Straighten controls for more precision.
Rotating Images with the Straighten Tool
Rotating an image with the Straighten tool is as simple as selecting the tool and dragging
within the image to make it straight. However, it’s important to understand that although
the image appears to enlarge as you rotate it, Aperture actually crops the image so that it
fits within its rectangular border without blank edges appearing on the sides.
To straighten your image using the Straighten tool:
1 Select an image.
2 Select the Straighten tool in the tool strip or the Full Screen view toolbar (or press G).
The Selection tool changes to the Straighten tool.
3 With the Straighten tool selected, drag within the image to rotate it either clockwise or
counterclockwise.
As you rotate the image, a yellow grid overlay appears to help you make the horizon
perfectly straight, and the image is cropped to prevent gaps from appearing in the
corners of the image.
Note: It’s a good idea to turn zooming off when straightening an image, so that the full
image fits within the Viewer. If an image is zoomed in to actual size, you can turn off
zooming by clicking the Zoom Viewer button in the tool strip or the Full Screen view
toolbar (or pressing Z).
