This round sphere is generally called Orb.

There are several kinds of Orbs informed, but the most often reported is a small light source defocusing.

The matters in the back are well focused and because of this, you may not understand why we pick up defocusing. However because back ground is clearly focused, the light source in near side, just in front of the lens for example, is out focused.

So what is this small light source? In many cases, they are dust floating in the air. When lighten by any strong beam, the dust become the small light source, and when taken by photo focused on the far side, these dust in the air become unfocused then blur and appear like orbs in the photo. Please take a look of sequential photographs.



This is a mirror with dust. We took photo of mirror focusing to the matters reflected in it. As you can see, as the mirror approach the camera lens, the dust turn into Orb-like- shapes.



The technique is simple. All you need is a small light source defocusing and it does not have to be some dust in the air. “Rain drops” (Upper left and middle photo),”Small water drops adhered on lens”, (Upper right photo), light far away when the focus is put on the near object works as well. So before you call them an Orb and a spiritual phenomenon, you should treat them with reliable attitude.
