After comparing the black and white photo to the color one, I seriously believe that the face and body outline are reflections off of the dented and scuffed stainless steel. To convince me, you would have to drape up a black piece of cloth over that part of the yeoman's office and take the photos, again. Anything white that would show up would obviously not be a relfection at that point.
There have been times when I am in the control room and I think I see a visitor standing in my peripheral vision, but when I look, no one is there. There is so much clutter in that area, though, that I often dismiss it as my mind mistaking equipment for a person. I'm not creeped out or anything. The girl/lady that thought she saw someone probably had a similar mind trick. As you guys said earlier, when you're looking for this kind of stuff, your imagination can really kick into high gear. These ghost hunters probably "see" ghosts 24/7.
Now, the Ghost Hunter show has really caught some creepy stuff on film. Especially on the Queen Mary. I'm not sure if our boat is really worthy of their talents. It would get publicity, but we don't need Goths and other freaks visiting the boat to talk to spirits or looting it, because they thinks it's cool - like what happened to the town in MD that they filmed the Blair Witch Project in.
