The Anamorphosis panel corrects distortions that are created when using a wide angle lens. Objects or people can become flattened or stretched when placed at the edges of a picture – this is a cylindrical volume anamorphosis. If the person is placed near a corner of the image then the distortion can become a diagonal distortion – this is a spherical volume anamorphosis. The anamorphosis correction neutralises both types of distortions, experiment with both types to see which works best on your image.
Use the Horizon correction to correct photos with slanting horizons or leaning uprights. Click on either the horizontal or vertical icon and a single straight line is placed on the image. Align this with the horizon or vertical object in a picture and the image is rotated to make the correction. Images are rotated in 0.1 steps from -90 to +90 degrees.
Cropping is automatically applied to the image, although you can turn this off if desired. The image canvas can be stretched in several directions to correct a perspective problem, which means your final photo may not have the same dimensions as the unaltered version.
The Auto crop worked flawlessly on every image, even the ones with extreme corrections applied. Allow sufficient space around your subject for cropping when taking the picture.
If you have ever had to copy a painting then you may know just how awkward it can be to square things up in camera. With Viewpoint and the Rectangle Keystoning tool, squaring up copy work is quick and easy, just place an anchor point on each corner of the artwork and then click the apply button, it took less than 30 seconds to square up this ancient wall painting.
