Using a Wide Angle lens (like I did when photographing Brentor Church) can cause distortion in the outer areas (top, bottom and sides) of your images.
Now this is good to keep in some areas of our images such as in the foreground to emphasise that area HOWEVER there may be some areas we don't want it.
So, here's how to quickly Quickly Fix Wide Angle Lens Distortion using PhotoshopPhotoshop PLUS why I didn't do it in Lightroom or Camera RAW.
Enjoy,
