HDR is something Chad and I have incorporated into our work flow over the last couple of years. So, what does HDR mean?

Here is what Wikipedia has to say:
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminance between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods. This wide dynamic range allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.[1]

Basically, HDR means that we can pull out detail in shadows and dark areas that the camera can't get in a single exposure. The human eye can see these details but our camera sensors can't.

Here are the 7 images I used to create the image on the top of the page.

Many people haven't jumped on board with the emergence on HDR. In my opinion HDR is here to stay. HDR has helped Chad and I bring our landscape photo to a whole new level.
