A photo by the reddit user Two-Snap, who appears to have deleted his or her account in the meantime, so I can't link to the source. I don't even know what I am looking up (Burnt wood in the desert? How does that happen?), but I like the simplicity of the composition, with clearly defined foreground and background. And the crescent moon is in just the right place. It's a pity that the wavy sand got cropped out for the landscape version.
I left everything as is because the colors were quite elegant and the contrast is nice, I only upped the sharpness somewhat.
A nice close-up of the mossy hexagonal columns at Proxy Falls. The photo is mostly a texture, but works nicely as a wallpaper. Sometimes, simplicity works the best.
Processing-wise, I only sharpened the image slightly.
