Rotating Images with the Straighten Controls
You can also straighten an image using the Straighten adjustment controls. Using these controls
provides more precision.
To straighten an image using the Straighten controls
1 Select the image.
2 If the Straighten controls are not shown in the Adjustments inspector or the Adjustments pane
of the Inspector HUD, choose Straighten from the Add Adjustment pop-up menu.
3 Change the value for the Angle parameter by doing one of the following:
•
Drag the Angle slider.
•
Click the left or right arrow in the Angle value slider, or drag in the value eld.
•
Double-click the number in the Angle value slider, then enter a value from –20.0 to 20.0
degrees and press Return.
Use the Angle slider and value
slider to straighten the photo.
Decreasing the value rotates the image clockwise, and increasing the value rotates the
image 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 o when straightening an image, so that the full image ts
within the Viewer. If an image is zoomed in to its actual size, you can turn o zooming by clicking
the Zoom Viewer button in the tool strip or the Full Screen view toolbar (or by pressing Z).
