dude, you're clueless. take it from a guy who's been shooting for over 20 years and professionally for half that... the big, well exposed moon would never show up like that in those low light situations on film. It shows up exactly like what you seem to think is the sun or whatever- overexposed and blown out.
Also, what the hell are you talking about a sun dog for? image google it so you know what it looks like. sun dogs show up under thin hazy cloud conditions and are merely rainbow like circles around the sun. How does that even remotely relate to this pic?
