There's a lot of debate going on in the paranormal field about orbs. Some paranormal teams will post photos of orbs that they know are nothing more than dust or reflection.
We at  P.I.T.O.N. have posted some pictures of orbs. The orbs in these photos are nothing more than dust or reflection. These photos have been DEBUNKED!!!! by our team. We only post photos of orbs if we have doubt as to whether or not its dust or reflection. A true orb is  an energy sphere. An orb is not a spirit. You'll notice that the woman in the first photo has nothing around her. The second photo shows the orb traveling across her arm and the third photo shows the orb traveling down her leg. In the 3rd photo she has leaned slightly .Whats your opinion? We at P.I.T.O.N. feel its a bug.
Nothing more than reflection off of the recorder on the desk. Yet some teams will post photos like this and call it paranormal.
This photo looks like a black figure with a bunch of faces.This is nothing more than matrixing.This was nothing more than burned wood
No its not a Spirit...No its not a Ghost..No its not an Orb...Its the strap on the camera. Yet People like the owner of Vegas Haunted Tours will  show photos like this and tell people its ectoplasm moving through someone.
Dust or Reflelection
