When you’ve taken bracketed shots using your camera, the next step is to apply a process called tone mapping. This involves assigning one series of colors to another to approximate a greater dynamic range than a camera is normally capable of perceiving. Software packages like Photomatix Pro can automate a lot of this for you. Just load your images into the software and initiate the process.
