Lightroom 4 Public Beta: What's New
 |
With the release of the Adobe Photoshop Lightroom 4 Public Beta, new and current users have the opportunity not only to explore the the latest additions to the company's database-driven image editing and workflow tool, but to provide feedback to Adobe and help shape the final release.
The Lightroom 4 beta introduces quite a list of features, including a completely new book-creation module, expanded support for video, soft proofing capability, and geo-tagging of still and video images via a Google Maps-powered module. Image editing tools have also been significantly updated, with a new process version (PV2012) that includes a reworking of the Basic panel controls and new localized editing options.
To get you up to speed on what's new and help you start exploring the public beta, I'm going to take you through the tools and features that have changed since Lightroom 3. Keep in mind this is not a Lightroom review or tutorial, rather an illustrated overview of what has been added and updated. My goal is to help you get started in exploring these new features for yourself.
We'll take a look at the following features:
System requirements
Before we get started it's important to note that the minimum system requirements for Lightroom have changed. Lightroom 4 does not support 32-bit Macs. You must be running a 64-bit Intel processor and OS 10.6.8 or higher (read this Apple support document to determine whether your Mac has a 64-bit processor). On the Windows side, support for Windows XP has been dropped. Lightroom now requires a version of Windows Vista or Windows 7.
Develop module

Lightroom 4 introduces Process Version (PV) 2012. What's a process version and why should you care? Well, it's the image processing engine behind Lightroom (and Photoshop's Adobe Camera Raw plug-in). The Lightroom engineers make periodic tweaks to its components to provide better image rendering and/or enable new editing functionality. While the rendering performance sees some minor changes, PV2012 stands out by introducing a redesigned and recalibrated set of the Develop module's Basic panel tools, along with more localized editing options. Simply put, PV2012 is of huge consequence for every serious Lightroom user. Its changes are significant and will have a direct effect on your editing workflow.
As with the introduction of previous process versions, Lightroom, by default honors the current (in this case PV2010) process version of your existing images. If you desire, you can simply go on working as you always have. But should you choose to update an image to PV2012, a whole host of new functionality awaits.
Basic panel
Select any image in the Develop module that was imported in Lightroom 3 or earlier and you'll notice a warning icon in the lower right (shown below), indicating the image has not been updated to PV2012.

After clicking the icon you can choose to update the selected image or all images in the filmstrip. Once an image is updated to PV2012 you will notice a revised collection of tools in the Basic Panel (shown below), as well as a noticeable change to the appearance of your image.
Gone from the Basic panel are the Recovery, Fill Light and Brightness sliders. Instead, what you see in Lightroom 4 is a separate grouping of sliders labeled Highlights, Shadows, Whites and Blacks. Moving any of these sliders to the right (a positive value) brightens pixels. Negative adjustments darken pixels. The default value for all items in the Basic Panel is now set to 0 for raw files, just as they have always been for JPEG images.

It's very important to understand that for many of the Basic panel tools, the internal effects ranges have been changed, meaning that a slider value of say +50 in a PV 2010 tool may not correspond to +50 in the equivalent PV2012 tool. When updating PV2010 (or earlier) images which already contain manual Basic panel adjustments, slider values will be carried over or 'transposed' to the appropriate PV2012 settings. But the appearence of your image will change, often significantly. For this reason, I encourage you to apply PV2012 on an image by image basis to your existing photos to get a feel for what the new tools can do. Or simply import new images, which will automatically get the newest process version, and explore the new features with those images.
White balance
The WB selector's sample area is now zoom-dependant, mimicing the behavior seen in Adobe Camera Raw. Clicking with the WB tool on an image displayed in say a 1:2 (50%) view will result in a white balance calculation based on a wider range of pixels than performing the same action with the image at a 1:1 view. Put more simply, when you adjust the Scale slider for the WB selector's loupe window, the image area you see in the grid is now the same area that LR will sample to determine WB.

Setting the Scale slider to the lowest possible magnification results in a wider area of pixels from which to sample. |
Sampling over a wider area of pixels should lead to more accurate WB settings in noisy images by minimizing the impact of random pixel values. In previous versions of Lightroom, a consistent grid of pixels was being sampled regardless of the image view or Scale slider setting.
