Using Lens Profiles

Adobe’s lens profile corrections are amazing. Lens Corrections automates correction of standard lens distortions, including geometric distortion, chromatic aberration and vignetting. This feature also can be used to adjust perspective and rotation. Adobe provides support for a growing list of camera manufacturers, camera models and lenses—Canon, Nikon, Pentax, Samsung, Schneider, Sigma, Sony, Tamron and Zeiss.

Using Adobe’s Lens Profile Corrections

You can access Adobe’s Lens Corrections in three locations—Adobe Camera Raw, Lightroom 3 or Photoshop CS5’s Lens Corrections filter. Lens profile corrections were first introduced in Lightroom 3. To get lens profile corrections in Adobe Camera Raw CS5, you need to download a version that has been updated after the release of Lightroom 3. You can download the latest free update at

It’s far less destructive to make these types of adjustments to raw files during conversion rather than after conversion; it’s also more flexible. Use a smart object and go back to the controls anytime by simply double-clicking the smart object. However, if you want to apply Lens Corrections within Photoshop after a file has been rasterized, you can use CS5’s updated Lens Corrections filter.

2) Distortion at maximum.

In ACR and Lightroom, you’ll find two tabs under Lens Corrections, Profile and Manual. Under Profile, click Enable Lens Profile Corrections to activate this feature. Using the EXIF data in your raw file, the software automatically will select the make of your camera, the model of your lens and the profile for that lens. You can use the supplied lens profiles, download a custom profile made by another user or create your own manually or with Adobe’s Lens Profile Creator.

Checking Enable Lens Profile Corrections also will allow you to access three sliders—Distortion, Chromatic Aberration and Vignetting—for manually fine-tuning the results. If you like the results of one correction but not another, you can decrease or increase the effects in one or more of the three fields. Under Manual, you’ll find controls for visually creating your own lens profile corrections.

Vignetting offers two sliders: Amount, or the intensity of the adjustment, and Midpoint, which is designed to control the way the effect fades off. Chromatic Aberration offers two sliders: Fix Red/Cyan Fringe and Fix Blue/Yellow Fringe, plus a Defringe drop-down menu with three options: Off, Highlight Edges and All Edges. The Defringe menu options can be used to target the adjustment more precisely. Highlight Edges is particularly useful for defringing images with strong specular highlights.
