Huh? We know the internet is filled will a wonderland of images. Google Earth is my playground where I scourer earth's surface to carve out my own piece, then process and present. This image is from Mars equivalent found at hirise.lpl.arizona.edu. I ask myself if I can call this photo my own. Finding images like this is the proverbial needle in a haystack and then there is the postprocessing. So, in the end, I think of it as a collaborative process.
