I read this and decided to look at the photo that appears to be "spot lit"
and found that indeed the area behind didn't appear to be evenly lit. I am a professional photographer and I know this, to appear evenly lit the area behind him had to be of equal reflectance..... take a look at http://www.hq.nasa.gov/office/pao/Hi...1/20130774.jpg you can see the surface varies greatly. Same as the background of a model on a white sand beach would appear spotlighted if the area beyond the beach, in the frame and out of focus was volcanic. Sorry to point this out, there are many here that are much more qualified than me to point out flaws in this, but I do know a few things about photography and this was blatantly obvious once I looked at some other pix showing the area around the lander.

David Percy, the photographer whose opinion Nathan Jones has borrowed, doesn't seem to know much about lighting. I have yet to show his arguments to a professional photographer who doesn't immediately fall down laughing at them. But back to the point. Surface color will indeed play a part in the apparent brightness of an image, but so will surface contour and texture. Have you ever shot landscapes in the early morning or late evening? If you wait for just that right second, the low lighting angle will reveal very subtle contours that don't show up at noon. Or conversely, wad up a piece of paper and then smooth it out and lay it on a table. Then light it artificially from a low angle. You get to see all the contours because of the difference in apparent brightness. Nathan Jones doesn't know much about lighting, in case that's not obvious already. He is completely clueless about the effect of texture and contour on apparent brightness. He strangely claims that the lighting should be uniform across all the terrain. Obviously he doesn't spend much time looking at terrain. -- | The universe is not required to conform | Jay Windley to the expectations of the ignorant. | webmaster @ clavius.org |

![]() Have you ever shot landscapes in the early morning or late evening? If you wait for just that right second, the low lighting angle will reveal very subtle contours that don't show up at noon. Contour would be a main key, just a slight down slope would be a very dramatic change in lighting, you can tell the sun was pretty low. The moon has hills and valleys just like Earth. Sad that some people have such negativity that they can make up their own science to support their thoughts...but then again history is full of that |
