High Dynamic Range Imaging with the Sigma DP1x by Jack Howard » Detail
Here is a 100% pixel view of the sharp-focused area of the above photo. Notice how clean the pixel values are from darkest to lightest areas of this frame, which is a great advantage to HDRI workflows for stationary subjects. Done properly, HDRI can be a naturally noise-diminishing workflow for every image from every camera. Of course, the better quality the source images, the better quality the results, and the DP1x lets you start with excellent quality source images.
