If you keep up with fstoppers, it's likely you saw some unique portraits posted HERE using the Brenizer Method. This post explains that method a little more. If you want to hear Ryan Brenizer explain his own method, he posted his own video on his website. If you you're too lazy to watch the whole thing though, here's a summary with some examples.
The fundamentals to creating a "Brenizer" photo is to take a panorama portrait at a shallow depth of field (ie using an 80mm lens at f1.8) and stitching it together in photoshop. The result gives you a wide angle picture with a depth of field not possible with any wide angle lens. Check out some of these stunning examples below.
