Lightroom Lens Correction: how to fix common lens and perspective problems
Apr 2nd 2014, 23:01, by jmeyer

The Lightroom Lens Correction controls offer a powerful, yet easy-to-use, tool to fix troublesome imperfections. In this Adobe Lightroom tutorial we’ll show you step-by-step how to use it.

Lightroom Lens Correction: how to fix common lens and perspective problems

With Lightroom's range of powerful tools, fixing lens and perspective issues is a quick and easy affair. This month, we'll look at a few common problems.

First off, there's distortion in our factory scene, with the wide-angle lens making straight lines look bowed.

Lightroom has a database of lenses with information on distortion issues for particular lenses at specific focal lengths, so as long as the lens is included in the image EXIF data (it will be if you shoot in RAW) then fixing distortion is a single-click job.

Chromatic aberration can be a problem, especially with cheaper lenses and wider apertures.

Again, this is usually a one-click fix, although if you want precise control then Lightroom 5 lets you choose which colours to remove.

Finally, there are the Upright buttons. With these impressive tools, fixing keystoning, camera tilt and perspective problems has never been so simple.

03 Use Upright buttons
Zoom back out, then go to the Basic Tab in the Lens Correction Panel. Click each of the Upright buttons (Auto, Level, Vertical and Full) to see how they affect the image. Auto works best. It corrects any camera tilt and aligns all the vertical lines.
