Orbs appear as opaque or semitransparent round or oval areas on the photograph and are generally white in color although other colors are occasionally reported.

In the photo on the left, the claim was that a mysterious orb was seen floating at the top left edge of the graveyard.
A spectral presence trying to maintain a grip on the real world???

However, the second photo clearly shows the ghostly orb for what it really is a Stop sign.

Now, the sign may be at the end of a phantom road.. but it's still just a Stop sign!
