This document provides a tutorial for creating a high dynamic range (HDR) photo using Adobe Photoshop CS5. The tutorial involves taking an original photo layer and duplicating it, with one layer adjusted to black and white with an overlay blend mode and gaussian blur added. A third layer of the original photo is added on top with a linear light blend mode. Adjusting the opacity of this top layer blends the layers together to increase the contrast and create an HDR effect beyond what a single photo capture can achieve. The result is a photo with a wider dynamic range and more highlights and shadows visible than the original.
