I was able to take advantage of this extremely overcast day and play with my long exposures. This one is only set to a 1sec shutter speed but as you can see it was starting to get a little to bright to open it for much longer than that.
I stacked three separate exposures (-1,0,-2) and a monochrome black and white for texture, on top of one another for the HDR aspect. I accomplished that using Photomatix pro.
I also decided to lean heavily on all the colors from the rocks and the stone wall by pulling our the major spectrum elements using Photoshop CS6.
