I had another interesting evening recently on a UFO/Orb tour. This stunning Orb photo was taken that night. It is not dust, rain or snow, nor is it a defect of the camera or a particle of some sort stuck on the camera lens.
When we took random flash photos that night fascinating objects began to show up. They were about the size of soft balls and were a bright white color. Some were moving fast and some were stationary. The really unusual part of this is that the camera flash would light them up and the objects could be clearly be seen by the eye but not recorded on the camera. Its usually the other way around.
I am not sure if the soft balls were Orbs or not but it freaked out one of the people on the tour so much that he said " We are getting out of here now!" This has happened before, recently.
I was having a great time and to me they were just fascinating. But... another night.
