I’ve caught “orbs” (no double entendre intended) plenty of times even on film. Oddly, this seems to happen most often when there are shiny surfaces within the range of the flash or when I’m shooting in the studio and using strobe lights. Mind you, it’s true that once I move the shiny things or move my strobe lights back so they are behind me and my camera, as the cynical consultant I checked with advised, the orbs…disappeared. But I think that’s just because moving the shiny things and the strobes upset the harmonic balance or something. Right?
You know that is right, don’t upset the orbs, they will fry you with their energy beams and dip you in sweet and sour sauce for you taste good that way.
