When I got into the field of paranormal research, I was overwhelmed by the amount of people in this field who claimed orbs were paranormal in nature. I don't know how many videos and photographs I have seen as well as websites that devote their whole time to the explanation of orbs and their connection to the paranormal. The one thing that bothered me was the fact I never saw any of these groups provide proof of their claims!
I will state for the record, I am a skeptic. However, I am a skeptic with an open mind. I am willing to look at the facts and evidence. I will even experiment with a concept in an attempt to find the answers. I like many of you here have taken thousands of photographs and so far maybe one of those photographs depict anything that might remotely be paranormal in nature. I have quite a few photographs where I have captured orbs, but never once did I ever think for a minute those were anything other than dust, bugs, moisture, etc. There was just no evidence linking the two.
I began checking into this orb phenomena and found that many of the orb photographs came into vogue with the advent of the digital camera. Once the flash was moved closer to the lens, these cameras began to document this debris onto the media in the form of an orb. In fact an excellent website is the Association for the Scientific Study of Anomalous Phenomena where they have a lot of literature on orbs.
Just because we investigate in locations that people claim to have paranormal activity taking place does not mean natural occurrences, such as orbs, can be construed as paranormal. If we make a claim that something is paranormal we had better be able to show that claim to be valid and backed by evidence properly collected and analyzed using critical thinking.
I have yet to see any evidence to change my mind that orbs are paranormal in nature. As I said earlier, I am an open minded skeptic willing to look at any possibility, but I am not so open minded that I let my brains fall out and accept any claim.
