Have you ever taken an image and then noticed slight distortion and heavy, dark corners? Often, this is an easy fix. Head down to the Lens Corrections Panel on the right side in Lightroom. Under this panel, you'll see the option to Enable Profile Corrections. Enabling Profile Corrections enables automatic corrections based on the lens used so as long as Lightroom supports the lens you are using, checking this box will automatically apply the correct Profile Corrections to your image. Watch what happens to the dark corners of this image upon Enabling Profile Corrections.
