Since Lightroom version 3, Adobe has been providing a Lens Corrections sub-module within the Develop Module to correct various optical issues commonly seen on all lenses. It is a very powerful and complex tool that can be applied to one or many photographs with a couple of quick steps, potentially saving many hours of post-processing time. In this article, I will explain what the Lens Corrections sub-module is, how it works and how you can effectively use it to correct optical issues in your photographs. I will also show you a method of adding a lens profile manually, if you have unsupported lenses in your arsenal.
1) What is Lens Corrections in Lightroom?
Lens Corrections is a tool within Lightroom’s Develop Module (hence I often refer to it as a “sub-module”) that allows fixing such lens problems as distortion, chromatic aberration, vignetting and perspective correction “non-destructively”, without leaving Lightroom. The beauty of the Lens Corrections feature in Lightroom, is that just like any other setting, lens corrections can be copied from one image to another, applied to hundreds of images at once, or can be set up as an import template, automatically applying corrections to images during the image import process. Keep in mind that lens correction is not a simple fix that applies to any lens – corrections are lens-specific. Since each lens model is designed with a unique optical formula, lens corrections must also be uniquely customized for each model. For example, one could not take a lens correction from the Nikon 35mm f/1.4G and apply it to the Sigma 35mm f/1.4G just because they share the same focal length and maximum aperture. Adobe staff spends time working with a number of different lenses and they continuously add support to new and existing lenses when new versions of Lightroom are released.
