People often make the argument, "well if they are just dust, then why don't we see them all day long?" Simple. It's because these microscopic pieces are not illuminated. They are so small they are nearly invisible in ambient lighting. The next time a sun ray comes through your window, like a concetrated beam, get down next to it and check it out. Fluff your blanket, shake your hair, sneeze, walk across the carpet. What do you see? Dust, pollen, and other air particulate is everywhere.
Have doubt about the "dust level" of a room? When you go to take a photo, simply look just beyond your flash from behind your camera. As the flash shines, you can see the dust zooming back and forth. When all else fails, take a bright flash light point it across the room, and look into the beam.
Taking photos in an overly dusty area, is kind of like doing an EVP session during a party. If the environment is contaminated, how can you tell whats paranormal and what's not? Even the cleanest person has SOME dust in their homes or businesses. We carry it on our clothes!
Then it's asked, "well I took two pictures! why is it in one photo and not the other?" Simple. These orbs you see, are much closer to your lense than you may think. Add the exaggeration of a convexed lense, and you can nearly cover the entire photo with 1 orb. Bright flash reflecting on a piece of lint very close to the lense can create a very large magnificent orb (in colors too!). In between taking photos so much as a fraction of a cm. can cause the dynamic of a photo to change. The smallest amount of our movement, microscopically speaking, can make a very huge difference. Plus, drafts and even something as simple as our own breath, can quickly move these small pieces completely our of range of shooting.
Before I started paranormal investigating, I admit, I thought these glowing balls were spirit energy. Shortly into my paranormal investigating career, I may have STILL thought so. But after years of sitting in the dark, at location after location, I cannot deny that I no longer support the orb theory. I've seen dust in photography in all forms. I'm confident in my conclusion.
Here is my response to the fan of our page who asked us our opinion of his photo.
