This tutorial will teach you two techniques for correcting both barrel distortion and perspective distortion in Photoshop.
The first method, which I use in most of my images, is quick, easy and uses the Distort function in Photoshop. I usually check Enable Lens Profile Corrections in Adobe Camera RAW before importing images into Photoshop. This reduces the barrel distortion. Then with Distort, I can nicely straighten the image.
The next technique teaches Adaptive Wide Angle. This tool is a strange one – it can be fairly easy to use and produces great results. Yet, sometimes, when images are more complex, with a good number of horizontal and vertical lines, things can begin to get messy. Hopefully in this video, I keep it simple enough so that you can use this tool to correct barrel and perspective distortion in many of your images when Distort doesn’t work.
