Dance Orb Ghost Picture

Marlene Bieber asked us to settle a dispute regarding orbs in this photo. Are they spirit or not? This has been an on-going debate by ghost hunters for years. It is true that orbs can be caused by dust, moisture, etc., so we will let our viewers decide. But, the positioning of the brightest orb in this pic appears special - coupled with the lack of spoking in the center, as a flash-reflection would create:

"I am very new with my interest of spirits, ghosts, etc. I have many of these "white circles" in a lot of my pictures I take of my family. My husband says they are nothing but something on my lens; and I am not sure if they are maybe orbs. Could you please set the record straight?"
