As I wrote last week, Lightroom 4 represents a big change—the biggest change to Adobe’s Raw processing engine since Adobe Camera Raw was introduced in 2003. They’ve completely revamped the underlying algorithms for all of the tonal controls, and changed the behavior, and in some cases the names, of all the Basic Tone sliders.

Overall, I’m really happy with the new process, especially for high-contrast images. But if you’re accustomed to Lightroom 3 the new tools may seem strange at first. So I’ve been working on two videos to explain the changes and how to work with the new tools.

The first video, embedded here, explains some of the differences between the old and new processes, how the new tools work, and the ways they affect an image’s appearance. Here are some of the main points:

– The automatic highlight recovery and black point setting in the new process (2:00)

– Why you should avoid updating older images to the new process—unless you want to start over (5:04)

– The new tools: some of the names are familiar, but they all behave differently (7:30)

– Starting points: the numbers are different, but the defaults are really the same (8:53)

– An in-depth look at each of the new Basic Tone controls and how they work (12:38)

This video is about 25 minutes long, so, as I say in the video, grab your favorite beverage, sit back, relax, and enjoy the show. I think you’ll come away with a better understanding of the strange but powerful new world that Adobe has created in Lightroom 4.

In the second video I talk about workflow in the new process. I show examples of processing both high-contrast and low-contrast images, talk about what settings you should start with, and discuss whether the new and improved Basic sliders can replace using curves.

I hope you enjoy this first video!
