HDR Photography
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
luminances between the lightest and darkest areas of an image than standard digital
imaging techniques or photographic methods. This wider dynamic range allows HDR
images to more accurately represent the wide range of intensity levels found in
real scenes, ranging from direct sunlight to faint starlight.
The two main sources of HDR imagery are computer renderings and merging of multiple photographs, the latter of which in turn are individually referred to as low dynamic range (LDR) or standard dynamic range (SDR) photographs.
Tone mapping techniques, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect.
Below are a few images I did some HDR processing on. They didn't turn out as good as I was hopeing for, but pratice makes perfect.
