2.8 Correcting Image Distortion: Adobe Photoshop CS4 video

This Photoshop how to video demonstrates correcting image distortion.  A wide-angle lens can distort an image by curving straight lines inward, especially when the photo is taken too close in range to the subject. This is called barrel distortion. A pincushion distortion causes the image to be pinched towards the center and is a lens effect associated with telephoto lenses. The Lens Correction filter can fix both of these lens distortions as well as chromatic aberrations and vignetting.
