1 Add a grid
Import TYLR16.dng into Lightroom’s Library. To see if
lines are distorted, it can be handy to summon a grid. Go
to View>Loupe Overlay and click Grid. Hold down Cmd/
Ctrl and click and drag on the Size and Opacity options
to customise your grid to suit the photo.

3 Set up a lens profile
Click on the Develop module. Open Lens Corrections.
You could go to Manual and drag the sliders to correct
distorted lines, but for quicker, more precise corrections
click on Profile, tick Enable Profile Corrections, and in
Lens Profile, click on Make and pick Nikon.

5 Remove vignetting
You can fine-tune the results by dragging the Distortion
slider, although the profile should do a good job. Toggle
the correction on and off and you’ll also notice that the
original corners are slightly dark. The profile lightens
them to match the rest of the scene.

2 Read the metadata

Toggle open the Metadata panel. You can see that a

20-35mm f/2.8 lens was used to take this photo. The

focal length was 22mm, and the camera was a Nikon

D700. Lightroom can use this data to work out where

the distortions will occur, and then counteract them.

4 Compare versions

The Lens Profile command reads the photo’s metadata

and then automatically selects the appropriate lens from

Lightroom’s list of lens profiles. Toggle the Enable Profile

Corrections box on and off to see how the profile

counteracts the original photo’s distorted lines.

6 Remove fringing

If you go to the Color tab you can turn on Remove

Chromatic Aberration. This counteracts colour fringing

around high-contrast objects with a click. Fine-tune the

results by using the eyedropper to sample unwanted

fringe colours, then adjusting the Amount slider.
