Ghost and Angel Pictures: Ghost in the Washington, DC Opera House

My girlfriend recently went on a trip to Washington, DC and was on a tour. I'm not completely sure this was taken in the opera house, but in any case, she went into the theater (she was the first one in), and sat down. She snapped a picture right as she sat down, just because she promised to take pictures of everywhere she went, and looked down at the camera. She said she was more baffled than shocked to see this image. Now, take into account that she was the only one there, the temperature was about 90 degrees, and this is a historic and public area. These facts completely rule out any possibilities, i.e. it being of a person running by, or of another image on the camera (she had none with people at the angle the apparition is shown at), or by her sitting down it created a heat ripple which caused some reflection of light (since her body temperature and the ambient temperature were nearly the same). Now, although this is possible and is being implemented in holographic uses, it is not the case since there has to be a very significant heat difference to create reflection of light (think of heat rising from the tar in the middle of summer - a mirage). Your body doesn't create this mirage because your body, the heat it emits and reflects, and the ambient temperature are so close. I think this is one fine, genuine piece of spiritual proof. What do you think? Really, I don't think I've seen anything more convincing, and as soon as I saw it I asked her if I could use it on here. We deal with this sort of stuff a lot (spiritual stuff), but this is the first "hard" piece of evidence we've seen. What's your opinion?
