The theme is Textures. I chose this particular picture because of the many textures it represents.
1. The area surrounding the Geyser is very crusted with calcium;
2. The texture of the trees;
3. The textures in the mountains; and
4. The softness of the clouds.
I have processed in Photoshop with a technique taught by Scott Kelby at a workshop I went to recently in Boston, it is a way to make it look like HDR but not be HDR.
We are on our way to a very Picturesque New Year!
