'Orb(s)' are a photography anomaly, usually noticed with Digital Cameras, that theoretically represents the “spirit” or “energy” of a deceased person. It will appear as a ball of light on film though is some cases; they are not typically seen at the time of the photo or video. Since there are many reasonable circumstances (dust, snow, rain, insects, reflection, Lens Flare, etc.) orbs still remain a highly controversial subject. They have also been seen using night vision goggles and are considered the most basic form of a spirit. Orbs provide the best evidence of a haunting. It should be noted to be careful of photographing refletive surfaces as these can create orbs in a photos.
