Nice photo, but the shot is backlit (as shown by astronauts shadows). If this is the case, why is astronaut's front flooded with brilliant light?
You and I differ on our definition of "flooded with brilliant light" but the simple answer is, he's standing on a fairly reflective surface, wearing a highly reflective space suit (had to be that way for cooling purposes) with the sun at a very low angle.
Complete balderdash. The reflectivity of the lunar surface is approximately equal to that of asphalt.
Also, his frontage is brilliantly flooded, the fact you try and say it isn't shows you're ludicrous.

It's the light reflected or scattered off the lunar surface. I wouldn't call it brilliant, it's very soft and is fainter that the direct light from behind.

Then by your logic (and very obvious lack of knowledge of photography, lighting, light bounce and light scatter), a person standing in a asphalt parking lot, turned away from the sun.....will not have their front lit at at? Or be very, very dark?
I see someone still has not learned about photography and lighting.

If the surface is so brilliantly reflective then why are the dark (away) sides of lunar stones/rocks not as well lit as the astronauts frontage?

Because light is mostly reflected upwards. The astronaut, standing tall above the surface, catches a lot of that reflected light, while the rocks don't, because they are lying low.

It's simple really. Think of angle of incidence. The ground is horizontal, the astronaut is vertical. A large portion of the light hitting the ground bounces away from the camera, a large proportion of the light hitting the astronaut bounces toward the camera.

The eye takes approximately 20–30 minutes to fully adapt from bright sunlight to complete darkness and become ten thousand to one million times more sensitive than at full daylight. In this process, the eye's perception of color changes as well (this is called the Purkinje effect). However, it takes approximately five minutes for the eye to adapt to bright sunlight from darkness. This is due to cones obtaining more sensitivity when first entering the dark for the first five minutes but the rods take over after five or more minutes.

I'm not sure, but I think the rock is the result of a big impact.

The rock was dubbed the House Rock because of its size. Apollo 16 astronauts had trouble determining its size and the distance to it because of the lack of atmosphere. www.hq.nasa.gov...
Here's the House Rock seen in the distance (the largest rock behind the astronaut): www.hq.nasa.gov...
And here's the video of the astronauts approaching it...

Thanks!! I've never seen the House Rock vid or the House Rock itself either. What else have I missed??? The house rock can probably be seen with earth-based telescopes, and if so, and it was "mapped" then that would be another proof of man's visit to a small semi-planet.

So... Where is this footage which demonstrates 1/6th gravity done in a vacuum?
