So what exactly is an “Adjustment Layer” in Photoshop, and what does it enable you to do? According to Adobe it’s “a layer that lets you apply color and tonal values to your image without permanently changing pixel values.” In basic terms, you can use various layers to experiment with color, tones, and more.

Most of my columns for this website concern the ideas and purposes behind the photographs I take. I always include information about the technology used to achieve the photos, which could be as basic as the f/stop chosen to direct your attention, or the use of a ND filter to make a long exposure possible. That approach is not incidental or coincidental; the stories are planned along those lines because my ideas come first, and technology’s purpose is to support those ideas.

What if we told you that by watching a five-minute video you can prevent Photoshop disaster—or at least save hours of frustration rebuilding an image you messed up by mistake?
