The following is my opinion on orbs that are captured on film. There are some people that will disagree with my view about orbs, and state that it is either a fault with the camera, or a trick with the light where dust particles cause this effect. That is fine as everyone is entitled to his or her own opinion, and as such, it is up to you to decide for yourself.
For me, orbs are spirit energies that are captured on film. These energies have been seen on still pictures taken with normal or digital cameras, as well as video cameras where they are seen moving. This phenomena has also been captured and witnessed on the satellite Living television programme Most Haunted. The orbs have not only been witnessed on film, but have been seen by the human eye as well. People can also see what seems to be sparks of light, and again I believe that these are spirit energies that are being witnessed.
The following are a few spirit orbs that I have captured on film, so please have a look at them and decide for yourself. If you are interested, then I suggest that you search the web for 'spirit orbs', where you will find other sites that will present different points of view. They may also show you other orbs that have been captured on film. If you are really interested the experiment yourself and see if you can capture this phenomena on your pictures as well.
