Digital photography isn't just about technology. Long before there were pixels, ISO settings, and layer masks in Adobe Photoshop, a set of artistic guidelines developed that help professional photographers create great compositions that engage the eye and elicit an emotional response. These guidelines for photo composition are easy to learn and can dramatically enhance your own photography. I'll cover composition in this slide show; for more fundamentals, read "Digital Photography Basics: Using a Flash" and "Digital Photography Basics: All About Exposure."
