Orbs...
Greg, first of all, congratulations on your beautiful home. I will surely plan to visit you in case I ever go to Georgia.
Greg, an eon ago I bought my first reflex camara, a Canon A-1. One of the warnings in the manual told about "closing" the eyepiece with a small side lever every time a time lapse picture was taken, to avoid room light getting into the picture through the eyepiece. When a time lapse picture was taken there was no eye pushed to the eyepiece to block the light from entering this way and getting into the picture.
This effect has thousands of times been mistaken for UFO's in time-lapse pictures people have taken and later seeing things in the pictures, most always blurred images, that were not originally in the image they shot.
Reading about UFO's, I once read about a lighted street night shot where a row of white aligned spots had mysteriously appeared in the picture, apparently from nowhere. The photographer instantly thought of UFO's. These white dots were actually the reflection of the back streetlights that had got into the picture through the eyepiece. The picture had been taken in the time lapse mode.
Most digital cameras are not the reflex type, only the most expensive ones are. Maybe this is the explanation why digital cameras shoot no Orbs. Is by any chance the digital camera you are using the reflex type? In this case, everybody I know takes digital pictures looking at the screen, with the camera quite away from the face. This could be the explanation of your orb in the first picture, it really seems like the reflection of a wall plate. Could this be possible?
On the other hand, I completely believe in everything that has been written in this thread! I have had my own personal experiences, and I don't accept anybody tellimg me that what I saw or what I experienced were a figment of my imagination!
