We have dedicated this page to one of the most intriguing aspects of ghost hunting, photographs. A ghost can present itself photographically in several different ways. The most common forms in which entities are visible on film are globes or globules. Another common anomaly caught on film is the ectoplasm, easily identified by it's swirling mist-like formation on film. Oftentimes, ectoplasms are accompanied by globes and globules.
Vortices are another strange photographic phenomena.
The vortex itself is a tornado-like visual in your photo. Much of the time, vortices appear to be a concentration of globes and globules. Also, they can sometimes cast a shadow in the photo. It is theorized that the vortex may be a means of travel for ghosts, a portal so to speak. Unbeknownst to most, the least common photographic evidence of ghosts is the apparition.
