Yeah, that is pretty sweet. One of the few examples of HDR that actually works nicely IMO. Well done indeed! :victory:
Not HDR, that image is blended by hand using layer masks and fuzzy brush.
There is a gaussian blur overlay kicking up the contrast and saturation, this is also blended in by hand only where and how much I think improves the image.
HDR images tend to destroy shadows and contrast, and leave halos around objects, I actually like shadows and contrast in my images.
I use HUGIN to do my stitching, GIMP to do the final blending.
Here are a couple from Cortez Colorado looking up at Mesa Verde taken from the same spot, first in March of 2006 and second in September of 2006.
