High dynamic range photography is a form of photography that allows different levels of light in pictures to be put together into one image to give a scene a more real, and sometimes surreal, look. Usually one will take three or more images with one being overexposed, one underexposed, and one at the correct exposure. These images are then put into a program to render them together. I have been using Photomatix pro to render my images, but this is also possible with programs like Photoshop.
