Hi Bohne....
From what I gather, those blobs are sopposedly orbs. Now, if I'm not mistaken...(sometimes I am..lol) It can either be specs of dust on the lens of the camera, or sopposedly ghost.
I have a few pics where there were orbs in mine also...some claimed it was the lighting, some claimed it was dust. These pics...umm, not sure. One in particular...definetly shouldn't have showed up like it did.
Like this one in this photo..lol So..who knows........?
