Clarity vs. Sharpening in Lightroom
Written by: Tiffany Joyce
One of the last steps that we perform in post-processing is sharpening our photos. I find myself to be a greater fan of “clarity” when post-processing in Adobe Photoshop Lightroom 4 (or Lightroom 3), and apply it with a more liberal hand than I apply sharpening. But what is the difference between clarity and sharpening?
I’ve written about sharpening before. In a nutshell, Lightroom and other post-processing programs determine the where the edge lines are in the photograph by looking at the demarcation between lines of light pixels and lines of dark pixels. Sharpening is achieved by lightening the pixels next to the light lines, and darkening the pixels next to the dark lines. This creates greater definition along the edges of the subjects and details in the photograph, which translate into a sharper images as seen by our eyes.
Clarity adds mid-tone contrast to the photograph, which results in an emphasis on textures and details. It also results in adding much less noise to the photo than would occur when using the sharpening slider. It’s easier to demonstrate than to explain, so take a look at these photos (click on any of them to view larger versions).
This is a photograph of MotoGP rider Jorge Lorenzo at the Indianapolis MotoGP this past August. This is SOOC, with the exception of some cropping.
Zoomed in, in Lightroom:
This is the same photo, with the Clarity slider cranked up to 100:
Zoomed in, and note the difference in the Histogram:
Here’s before and after again, side-by-side – notice in particular the change in detail on the helmet and in the grass:
The photos above demonstrate that a subtle effect can be achieved, even when clarity is “cranked up”, because there isn’t a lot of texture in the shot. The photos below of mountains in the Snowy Range of Wyoming have a lot of texture and therefore achieve a dramatic effect when clarity is applied. The first shot is straight-out-of-camera, and the second shot is with clarity at 100%:
In both instances, I would probably use a clarity level of about 50 rather than slamming the slider all the way to the right. I do really like the effect, and I like having another option to add distinctness to my photos.
