Simple, look at all the creators and depending on how you view it the right, possibly raised side of them in all cases has the light side on the right. I assume there are lips on all those creators and if the light were coming from the left thos black bases would be lighter on the right side but with a lower cast. Like I said, it is possible that we look at those pictures from a different perspective. You might be right and since I'm not up there I don't really know but it seems to me that since the only really detailed shadow is of the Eagle. Doesn't really matter because I'm not a denier, and never have denied that they actually went to the moon and walked on it, but this picture just doesn't look right to me.
Just my opinion and if I saw it that way, others can see it that way as well and that was what I was trying to convey.
