Lens corrections – digital

No lens is perfect. All lenses display aberrations to some degree, including distortion, chromatic aberration (colour fringing) and vignetting (corner shading). These are worse with cheap kit lenses or zooms, and eliminating them optically is both difficult and expensive.

So it's often more effective to put up with these slight optical imperfections in the original lens design and fix them digitally instead.

An increasing number of programs  now offer automatic lens corrections which can identify the lens used to take a shot and apply a specially-calibrated correction profile from that lens. The better the software, the better the corrections and the more lenses are supported.

DxO Optics Pro was the first in this field (now DxO PhotoLab), though Lightroom's lens corrections are really good too and Capture One Pro has profiles for a large number of consumer and professional lenses. These are probably the top three simply because they are RAW conversion tools you'd use at the start of your image-editing workflow anyway, but there are plenty of other programs which will fix your lens defects for you too.

Perspective Efex review

June 4, 2020 by Life after Photoshop

Verdict: 4.5 stars Perspective Efex is a really nice addition to the DxO Nik Collection 3. It offers geometric perspective, distortion and tilt-shift corrections in a simple, user-friendly interface.

Lens aberrations and what you can do about them

May 26, 2020 by Life after Photoshop

Aberrations, or optical imperfections, exist because no lens is optically perfect. Almost all lenses show aberrations from the ‘perfect’ image.

DxO ViewPoint 3 review

November 27, 2016 by Rod Lawton

Verdict: 4 stars DxO ViewPoint 3 is a very effective and useful add-on for DxO PhotoLab but perhaps less useful these days as a plug-in for Lightroom and Photoshop, given that these have pretty good perspective correction tools of their own. ViewPoint also faces competition from the new and very similar Perspective Efex plug in that’s part of the DxO Nik Collection 3.

How to use the Aperture chromatic aberration correction tools – and why!

November 25, 2013 by Rod Lawton

Aperture chromatic aberration correction

Chromatic aberration is the colour fringing you sometimes see around object outlines near the edges of the picture. With most consumer lenses it’s a fact of life, and as soon as you know what you’re looking for you can see the signs in many of the pictures you take. Some camera makers ‘tune out’ chromatic […]

Capture One keystone correction tips

November 20, 2013 by Rod Lawton

Capture One horizontal keystone correction

Keystone correction is usually used to fix converging verticals in architectural shots – that’s the most obvious use for the Capture One keystone correction tools – but this vertical keystone correction isn’t the only kind you’ll need. Keystone distortion happens when you tilt the camera relative to your subject, and this can mean horizontal tilt […]

When and why to use the DxO Volume Anamorphosis option

September 18, 2013 by Rod Lawton

DxO Volume Anamorphosis correction

DxO Optics Pro is designed to correct a range common lens distortions automatically, including distortion, chromatic aberration, vignetting and edge softness. But the DxO Volume Anamorphosis option is less well known. It’s not enabled in the default DxO corrections, but it can make a big difference to super-wideangle shots and shapes near the edges of […]

Straighten up your shots with the DxO Force Rectangle tool

September 11, 2013 by Rod Lawton

DxO Force Rectangle tool

DxO Optics Pro uses custom-made lens correction profiles to fix the distortion issues inherent in nearly all lenses, but it goes further than that – it can also correct the perspective distortion created when you photograph a rectangular object at a slight angle, thanks to the DxO Force Rectangle tool . You often don’t notice […]
