Let me start by saying my editing steps should have been different. I did not noise reduce the image until I was well into the editing progress and realized how noise the image was when I had to zoom in on certain parts. Noise Ninja gave me a hard time...it just didn't want to remove the noise no matter how high I made the settings, so I had to do a lot of cloning, patch tooling and airbrushing.

The first thing I did was check the histogram of the image and noticed that there was a high peak in the middle and next to no image content on either the low or high side, so I decided to try a curves adjustment. I used the eyedroppers in the curves palette to choose a highlight, midtone and dark spot. Took the highlight off the back of his neck, midtone off his fur and dark spot off the bottom of his nose.

I noticed there was a decidedly cyan cast to it so I desaturated the cyan.

I removed the distracting elements at the left and filled in color.

As described earlier I did a lot of cloning and painting.

Color still didn't look good so I tried desaturating green and that really fixed it up.

Ended with Smart Sharpen.
