Nope, none was added. I stopped doing that 2 weeks ago when I renewed my Photoshop. Here are the original photos, I zoomed in quite a bit and it distorted the resolution and made it blotchy and "watered" down. I however, did add Overlay and Gaussian Blur in Photoshop, which added contrast. The mud helped a lot so I didn't have to do much of it. So if you compare them together, all that appears to have been edited was the brightness.
