What are orbs?

They are most often the result of reflections of a light source within the lens. The light source may be in the frame of the shot or outside it. Modern lenses are coated to reduce internal reflections but they can still happen, especially when the subject requires a long exposure.

orbs can be one of a couple of things
they can either be reflections of light off an object such as dust or a bug
or the can be the physical manifestation of a spiritual entity
spirits are energy and when energy is concentrated together it can give off its own illumination
in either incidence they are not harmful

Well for the photographers they might just be reflection from the lens and angle of shoot of your camera. They are not harmful and they are just reflection from your lens.

But for Paranormal believers they claim this to be spirits caught on cam. They happen to be caught by your camera or they really want to show themselves on cam. Well I really do not know which to believe in that but one thing I know is that it has never been known to harm anyone.

I believe that orbs are spirits of some kind and they will not harm you.

I have caught many myself on camera. They were not there when I took the picture but on viewing the pictures afterwards they can be clearly seen. All the ones that I have captured have been in known hauted areas or buildings.

Most photo images called orbs are lens effects and reflections of glistening objects, dust particles and water vapor. Any photo taken in a dusty room should show you some good "orbs".

A small percentage of "orbs" are unexlained phenomenon. Objects picked up on camera that appear to be moving in an otherwise set shot and unusual shapes are two indicators that greater inspection is needed.

Some claim the energy produced by "spirits" is visible on camera in this way and although MOST "orbs" can be explained scientifically, there still exists a possibility that the camera is picking up something we can't yet explain.

In science it was the reflection of life on something like dust or bug....and the lens caught it...

but in paranormal it was an spiritual energy that manifest a certain area..they say that it was a harmful energy and some say it was dangerous..
