Extreme contrast edits in Lightroom 4 and ACR 7
1 Extreme contrast edits in Lightroom 4 and ACR 7
With the launch of Lightroom 4, Adobe formally introduced a new version of the raw processing engine that powers both Lightroom and Photoshop's Adobe Camera Raw (ACR) 7 plug-in. Known as Process Version (PV) 2012, it represents quite a radical shake up in the way you can now process your Raw (and non-Raw) images.
|The new PV 2012 controls offer the ability to create an HDR-ike tonal range from a single image capture.|
Adobe has offered several reasons for this change. With earlier process versions - PV 2003 and PV 2010 - there was a degree of overlap between some of the Basic panel tone controls, not to mention confusion among users as to the most effective slider combinations.
In addition, the default tone settings differed for Raw and non-Raw images. Different amounts of adjustments were therefore required depending on whether you were editing a Raw image or a JPEG for example, making it problematic to share settings between the two file types. So on one level PV 2012 is an attempt to make tonal adjustments more straightforward and intuitive to perform.
Above all though, the range of control when editing raw images was becoming somewhat limited by what the PV 2010 (and earlier) adjustment sliders would allow. The sensor performance of today's mirrorless and DSLR cameras make it possible to effectively extract a more extended dynamic range. The thing is, you need the raw processing tools to keep up with these developments. PV 2012 is Adobe's effort to do just that. In this article, we'll compare some of the raw file editing capabilities of PV 2012 against its predecessor, PV 2010.
What's changed in the PV 2012 Basic panel?
In PV 2012, there are still six primary tonal adjustment sliders in the Basic panel, all intended to be used in their order of appearance. But some sliders have been replaced and those that remain have seen changes in functionality. It's important to note that, unlike previous versions, most of the PV 2012 controls are scene adaptive, meaning their behavior - even at default settings - is optimized on a per image basis.

The Exposure slider is effectively a combination of PV 2010's Exposure and Brightness sliders. It is used set overall image brightness. The Contrast slider is now scene-dependent, offsetting its operational midpoint slightly depending on whether you are editing a low key or high key image.
Brand new Highlights and Shadows sliders offer separate luminance control for midtone-to-highlight and midtone-to-shadow regions, respectively (although there is a degree of overlap between the two). They work in both positive and negative directions and on an evenly balanced scale. So you can lighten or darken the highlights and shadow areas independently, with a +10 move being similar in strength to a -10 adjustment. The Whites and Blacks sliders are used to adjust the end points for the image's brightest and darkest tones, respectively.
Controlling a high contrast image with PV 2012
In the examples below, we'll take a look at the benefits PV 2012 offers over its predecessor when working on a high contrast raw image that contains a wide dynamic range. Here I'll be using ACR 7, which provides the same PV 2012 adjustments as Lightroom 4.
In the image above you can see by the histogram I've overlaid that the highlights are blown out and the shadow details are completely hidden. Because this is a Raw file, however, we can extract some data that would have simply been lost in an 8-bit JPEG.
While the PV 2010 edits are certainly an improvement over the original image, we are left with a somewhat flat looking image with muddy shadows and relatively little contrast in the background areas of the scene. And you'd be hard pressed, too, to argue that the slider adjustments I've described above are intuitive. Let's take another pass at the same file, but this time using PV 2012.
As you can see, the PV 2012 options give me greater control over the tones in the image in a more straightforward, though by by no means dumbed-down manner. In the crops that follow you can see just how much difference there is in using PV 2012 versus PV 2010.

Notice how much more shadow detail is visible in PV 2012's default settings. This initial rendering obviously provides a better starting point for extracting useful information.
|PV 2010 after editing||PV 2012 after editing|
At first glance the edited results may look very similar. But take a closer look at these crops (click on the thumbnails for a larger view) and you'll see that the PV 2010 image shows distinct halos around the column edges as well as false color in the clouds. Overall, the PV 2012 image offers a much more natural, 'less-processed' looking result.
