In April 2007, Photoshop C3 introduced the new, powerful Black-and-White tool. It can be used as an adjustment layer and features toning (or “tinting”). At the time, I was surprised that Photoshop did not implement the more powerful and useful split-toning of Lightroom. Toning is, after all, a popular treatment for photographs; many photographers tone shadows differently than highlights, and sometimes give the midtones yet another tone.
You could say that Photoshop features the ultimate toning tools: duotones and quadtones. This is true, but this method has its price. Once you use duo-/quadtones, Photoshop switches to a different color model, leaving the RGB workflow. I want to stay in the same color model (RGB), and I also like the toning process to be non-destructive.While an alternative would be to use the split-toning provided by third-party printer drivers, I want to do the toning and print the toned image from inside Photoshop.
