Chapter 8. Photo Editing and Enhancement > Correcting Lens Distortion

Correcting Lens Distortion

There are a few things you might want to address before you begin adjusting the color or contrast of your images. One of these things is lens distortion.

A camera’s lens can produce distortion. This is particularly true of zoom lenses zoomed to their wide-angle and telephoto extremes and of ultra wide-angle lenses. With telephoto lenses you can get barrel distortion, which makes your image look like it’s bowed around the edges. With wide-angle lenses, you can get pincushion distortion, which makes your image look like it’s pushed in in the middle. And fisheye distortion, which you get with ultra wide-angle lenses, makes your image look as if it’s being reflected on a sphere: Areas in the middle are enlarged while areas at the edges are compressed. Fortunately, all three kinds of distortion can be corrected with Adjust > Lens Correction.
