LENS CORRECTION
Lens distortion can plague wide-angle images. Notice in our example photo that the line along the top of the building below is bowed. We can go to Camera Raw’s Lens Correction panel and tick Enable Lens Profile Corrections to fix distortion and vignetting. Camera Raw automatically detects the lens used for the shot. Most common lenses are listed. For further auto corrections, there are the Upright buttons, found within the Transform tool. These help you fix converging verticals and wonky horizons.
