And the proof is in the videos. You just choose to believe otherwise. There are many such reflections in the Apollo 15 videos.
http://www.hq.nasa.g...15v.1195542.mpg - the clip we've been discussing. In addition to the reflections off the underside of the rung, look at the reflections in the thermal shielding and the side of the ladder at the very end of the clip.
http://www.hq.nasa.g...15v.1195800.mpg - reflection in the thermal shielding at the statr of the clip. At the 40% mark, similar reflection, and side of ladder is lit up.
http://www.hq.nasa.g...15v.1200031.mpg - 33% in, reflection in thermal shielding and ladder illuminated
http://www.hq.nasa.g...15v.1200330.mpg - 5% in, similar to above. Reflections caused by astronaut moving out of frame to the right (i.e. out of LM shadow, into bright sunshine)
http://www.hq.nasa.g...15v.1200916.mpg - 75% in, reflection in thermal shielding as astronaut moves in from the left in bright sunlight
http://www.hq.nasa.g...15v.1201156.mpg - Watch from 60% onwards. Look at the astronaut walking in front of the folding up lunar rover on the LM quad. When he's in the shadow of the LM, you can see his shadow on the rover, which gives an indication of how much light is reflected back onto the LM from the surface. As he moves out of frame to the right (and into bright sunshine), he is no longer casting a shadow, but is reflecting light both onto the folded up rover, and a panel above it on the LM.
Wherever you look in these videos, you see evidence of astronauts in sunlight reflecting off various parts of the LM structure, at a distance of several feet. You can choose to believe whatever your worldview dictates you must believe, but the evidence doesn't support you.
I've spoonfed you the evidence. See above for more examples. I can't help it if you don't like the taste.
They all do. Your 'interpretation' is the one that requires excuses (oh, there was some glitch that explains what we see here. Oh, it was a stage-light that just so happened to be pointing in that direction at the exact time required to create the reflection. Oh, let me refer to MoonHoax Believer Excuses 101, page 13, section 2...)
Ample. Sufficient. Enough. Plenty. An abundance. It matters not, since you choose to believe that you are right, and the evidence is wrong. That's the brilliant thing about faith, it doesn't require evidence.
