From article posted below:
One of the places that a Spirit likes to show up is in photos. This is because the camera is able to capture things that most of us cannot see with our naked eye.
Spirit orbs can appear in photos as balls of light, however sometimes it can be difficult to tell whether it is a Spirit or just a dust particle.
How Can I tell the Difference Between Dust and Spirit Orbs?
In order to determine whether it is simply some dust or a Spirit, here are some tools you can use-
Your intuitive senses– often our intuition is best at determining whether Spirit energy is present.
The density of the orb– the brighter and more dense the orb appears, the more likely it is to be Spirit, the lighter and fuzzier the orb, the more likely it is to be a dust particle.
Outer ring– Spirit orbs may have an outer ring or several rings within the orb.
The colour– dust particles are usually just one colour, whereas Spirit orbs can appear as many colours.
Use of flash– flash photography commonly captures dust particles that look like orbs.
There is no exact science to this, which is why your intuitive senses are going to be the most important when it comes to determining the nature of your orb.
Blue Orbs
Blue orbs are angelic and indicate the presence of powerful Archangels and Spirit Guides. Blue orbs are also very protective, and could also indicate a Guardian Angel. Sometimes these orbs appear in photos as a sign you are on the right track or as a confirmation.
