Not long ago Scott Kelby showed a series of portraits from his "Sessions" series—a look at photographers who also double as musicians. The series was a collection of beautiful black and white photos Scott produced as a personal project. In fact, the black and whites are really duotone images, and they look warm and inviting and wonderful. I must not have been the only person who thought so, because apparently lots of folks asked Scott how he created his great duotone effect. I used to do things like this in Photoshop, creating duotones, tritones and quadtones with immense control and lots of options in the powerful program. It turns out that Lightroom has a super-simple built-in way to create a duotone, and Scott happily published his info. How does he achieve it? He opens the split toning panel in Lightroom and adjusts the shadows hue and saturation. That’s it, all there is to it. Check out the screenshots, the specifics of the technique, and a link to the photos in the Sessions series, at Scott’s Photoshop Insider blog.
