Adjusting images 181
with cameras with fixed focal ranges, and in photos taken with
cameras that have low-quality lenses (such as disposable cameras).
Important! It is strongly recommended that you correct the lens
distortion in a photo before cropping it.
Types of lens distortion
Corel PaintShop Pro can correct three common types of lens distortion,
all of which make straight lines appear curved:
• Barrel distortion — Photo looks pushed out at the centre. For
distortion corrections to work properly, the axis of the camera lens
must coincide with the centre of the image.
• Fisheye distortion — Photo looks as though it has been pasted
onto a sphere or blown up like a balloon. The edges of the photo
look compressed.
• Pincushion distortion — Photo looks pushed in at the center
To correct barrel distortion
Edit workspace
1 Choose Adjust Barrel Distortion Correction.
The Barrel Distortion Correction dialog box appears.
2 Look for curved lines in the image, and straighten them by typing
or setting an appropriate value in the Strength control.
3 Click OK.
By marking the Preserve central scale check box, you can add or
remove pixels from the image, which changes the scale at the
center of the picture. Changes to the width and height of the
original image are displayed in the Result Size group box.
