I was walking across my business park in Atlanta and noticed the deep shadows at the edge of the park. I figured this would be as good a time to test out the HDR functionality of the phone as any. The first photo does not have HDR turned on. Notice the darkness of the trees around the edges of the photo.
The second photo was taken with the HDR turned on. Notice how much brighter and more balanced the photo is. Overall, I’m pretty impressed with the capability based on this limited test.
