ACDSee Pro 6 User Guide

3. Do one of the following:

Position your cursor over the edge of the crop window until it changes into a double-pointed arrow, and then drag

the edge of the crop window to the desired size.

Use the Width or Height spin box to specify a dimension for one side of the crop window. ACDSee Pro

automatically resizes the other dimension based on the ratio you selected.

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, click Perspective Correction.

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.

Correcting Lens Distortion

You can use the Lens Distortion Correction tool to correct barrel, pincushion, and fisheye distortion in digital photographs. In barrel

distortion the photo appears to bulge outwards from the center. In pincushion distortion the photo appears to shrink inwards

toward the center. In fisheye distortion, the photo appears to bulge outwards from the center, as if the photo were wrapped around

a sphere.

Barrel, pincushion, and fisheye distortion are common in photos that were taken with wide angle or zoom lenses.

You can save your settings as a preset for future use.
