Off topic for me, but shooting petroglyphs is a hobby of mine. Petroglyph photos tend to be brown on brown so I thought I would try to enhance the colors a little in Photo Paint. The colors you see are actually there (didn't add anything) just enhanced the saturation a little (well, maybe more than just a little). The bright orange you see is a type of lichen and is actually that color. In my own defense, Ansel would be doing the same thing if he was still with us. Thinking of producing posters, etc. Though I would see what you all had to say (wince).
