Correcting Perspective Distortion

You can use the Perspective Correction tool to correct perspective distortion in digital photographs. Perspective distortion is caused by wide-angle and telephoto lenses, which distort the perspective of large or far-away objects. For example, if you take a photo of a tall building, the building may appear to be narrower at the top even though the building is the same width from top to bottom.

To Correct Perspective Distortion:

1. In Edit mode, in the Geometry group, select Perspective Correction.

You can also access the Perspective Correction tool from the Filter drop-down menu or Filter toolbar.

2. An outline displays around the image. The outline has handles at all four corners, and in the middle of all the sides. Drag the handles to change the perspective.
3. Set the options as described below.
4. Do one of the following:
   • Click Done to apply your changes and close the tool.
   • Click Cancel to discard all changes and close the tool.

Click Reset to clear your changes and reset to default settings. If you saved your changes, you cannot reset your settings. If you want to discard only the Edit settings, select File | Restore to Developed.

Perspective Correction Options

Background color	When you correct distortion in a photo, the edges of the photo may bulge outwards or shrink inwards. Use the Background color options to fill gaps in the corners or sides of a corrected photo: Image: select this option if you want to fill gaps in the corners or sides of a corrected photo by placing the uncorrected photo in the background. This is useful if the gaps are small.
Show Grid	Select this option if you want to display a grid over the photo while you correct distortion. This is useful if you want to assess whether objects in the photo are straight.
