High Dynamic Range (HDR) Imaging

“In computer graphics and photography, high dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.” – From Wikipedia.

I have been testing a programme called Photomatix and have found it very easy to use, with examples and tutorials to boot. I also played around in Photoshop with the HDR merge tool (FILE -> AUTOMATE -> MERGE TO HDR) but didn’t find this offered as many options or control over the final processed image. I’ll post my attempts at HDR later, in the mean time check out the Flickr HDR Group.
