Of course when something really good does come up, a lot of people automatically assume it must have been faked. You just can't win I guess.
I wonder has anyone had success in recording orbs with other methods (e.g. FLIR)? Is movement a factor? If one takes a picture of an orb moving (blur) and you know the shutter speed it should be possible to calculate the speed the object was travelling at the time of the shot, given measurements of the other objects in the picture (and a range based on minimum and maximum distance from the camera). This would be an interesting experiment.
Nice post! If you will permit me, I would like to clarify one point.
Apophenia is more like perceiving connections between unrelated events. An example would be if someone heard a door slam and was convinced a demon had done it to taunt him about his brother's death by gunshot.
Pareidolia is the perception of faces or other distinct shapes and forms in indistinct images. The classic example is "bunnys in clouds." I believe that this is what you are referring to.
Anyway, I hope that this is helpful. If I am being a know-it-all, please just ignore me. :-)
