Propagating the belief that dust orbs are spiritual in nature makes the paranormal community look like idiots in the eyes of skeptics and denies us any degree of credibility.
"J___, please don't worry about the orbs in photos. They're not paranormal, they're totally harmless photographic anomalies.
"Frankly, it amazes me that people who should know better (i.e. those running 'ghost tours', or people in paranormal investigation groups) still treat orbs as paranormal phenomena. Often, they're just winding people up - giving the impression that something paranormal is happening when really there's nothing except dust. This is mostly to make their commercial activities seem more exciting, when, in reality, most of the time nothing remotely paranormal occurs during paid-for paranormal investigations or ghost tours.
"These orb thingies began cropping up in large numbers early this century, about the time people lots of people started using compact digital cameras. Here's an explanation of how orbs occur. (Admittedly, this article was written a good few years ago, before there were cellphone cameras with LED flashes, which produce orbs that look a little different, but the physics is the same.)
"With each different camera model and type you use, the orbs will appear different in colour, size, texture, etc. More professional-type DSLR cameras don't show orbs at all, which is why professional photographers are often puzzled by them.
"If you are lucky enough to see - with your own eyes, not the camera's - a little light source floating around in the middle of a room, then it may well be something paranormal! Take a photo of it; take heaps of photos; shoot a video. But the orbs that you can't see with your eyes but which keep appearing in your digital photos are easily explained, and they are extremely unlikely to be paranormal in any respect."
This part of my reply has less to do with the photographic orbs, but here it is anyway:
"Once we get thinking about a paranormal reason for odd things occurring (for example; a poltergeist as a reason for something falling or turning up in an unusual place), our minds naturally make the jump to attributing other, unconnected events to the same cause. But in all likelihood these things are totally unrelated. Looking at things more objectively requires stepping back from them, which is where paranormal investigators (sensible, experienced ones) can be of assistance.
"Please let me know if anything else interesting happens, or you get any more intriguing photos."
