I presume the latter, but these pictures were sent to me by someone who believes the former. The pictures were taken about 5-6 years ago on a cruise ship on a foggy day in San Francisco Bay using a Canon digital camera. The object wasn't noticed at the time the picture was taken. Supposedly the picture was taken outside and not through any window. I tried searching Google images and saw some camera artifacts that looked somewhat similar, but not really close, and the ones I saw seemed to be attributed to taking the picture through a window and getting the reflection of a light from behind the camera. Any thoughts on this?
