The Orb Phenomenon is taking the paranormal world by storm. The name orb is derived from the fact that the object is round and it appears to be a form of energy that is produced by a manifestation of a spirit in its lowest possible form. The orb can appear low to the ground or high in the sky. The object can appear and disappear in one place or actually move, it can also glow. Audio recording devices can sometimes pick up EVP – Electronic Voice Phenomenon at the same time as orbs going by this can be odd sounds or actual words. Orbs appear to be sneaky in that they will move around trying to evade capture on film.
Since the invention of the Digital Camera more and more Orbs are being photographed around the world and filmed appearing and disappearing using Infrared camcorders. Let me first say that 95% of all "orbs" you will see on a stills digital camera will be dust related. That’s not to say that a 35mm SLR with IS0200 film could not get one (in fact we have on a £5 disposable camera), it just seems to be easier to get them on digital due to the low costs involved (no developing) and the amount of photos taken especially at night with a flash (skeptics point to this as illuminated dust particles) but you can photograph them in daylight without a flash and get them but they are rarer.
