Figure 11-9. A classic case of barrel distortion. This photo has already been straightened with
the Straighten tool, but things are still out of plumb; notice how the columns and walls lean in
toward the top of the photo. You can even see a bit of a curve in the pillar on the far right. Bar-
rel distortion is the most common kind of lens distortion, and you can easily fix it with the Cor-
rect Camera Distortion filter.
