The technical photographic term for the occurrence of orbs, especially pronounced in modern ultra-compact cameras, is backscatter, orb backscatter, or near-camera [[reflection]].

==Cause==

==Cause==

Due to the size limitations of the modern compact and ultra-compact cameras, especially digital cameras, the distance between the [[lens]] and the built-in flash has decreased, thereby decreasing the angle of [[light]] [[reflection]] to the lens and increasing the likelihood of light reflection off normally sub-visible particles. Hence, the orb [[artifact]] is commonplace with small digital or film camera photographs.

Hence, the orb [[artifact]] is commonplace with small digital or film camera photographs.

Underwater photographers notice the effect also, which occurs for the same reason as above-water photographic artifacts. Sand, small sea life or other particles close to the lens, invisible to the diver, reflect light from the flash causing the orb artifact in the image. A strobe flash, which distances the flash from the lens, eliminates the artifacts.

==Paranormal interpretation==

Orb backscatter has been broadly interpreted as a highly variable range of [[paranormal]] [[phenomenon]] without verifiable causation, including invisible [[spirits]], demons, [[auras]], [[angels]], ghosts, [[energy]] fields, psychoenergetic artifacts, energy balls, etc.[1]
