A nice thing about HDR imaging is that the tonal range allows for lots of creativity. These images are an example of using Split Toning and Duotone techniques in Adobe Photoshop. This top grouping was split toned using Camera Raw with deep red and pale blue in normal along with low and high exposure versions. Notice how the different colors predominate based on the level of exposure.

Some photo artists would refer to these as normal, low key and high key. But the traditional use of those terms doesn’t normally apply to a simple shift in exposure as I did here. Using duotone is another way to get similar results though it takes more effort. This image required duotoning and additional Photo Filter work to get close to the same look as the first photo above. And as you can see, even though the two colors are well represented, it’s not as vibrant as the split toned version.  Too bad Adobe doesn’t offer split toning as a choice when creating a new fill/adjustment layer.Equipment used: Nikon D700 with 28-70mm f/2.8 lens set at 28mm, f/13, ISO 400.
