Here are a few examples of orb photographs: Not all "orbs" that appear in photographs are paranormal.
In my experience, many of the orbs that appear in photographs can be explained by the flash reflecting off dust, particles, insects, or moisture droplets in the air in front of the camera.
Theory #1 – Color difference in orbs is caused by "chromatic distortion" which is a fancy way of saying that our eyes perceive different wavelengths and shapes as varying colors.
Theory # 2 – Orb color difference is caused by the energy of the spirit who is represented by the orb.
For example, some ghost hunters believe that red and orange orbs represent a spirit who is angry or in need of healing.
Meanwhile, other subscribers want to know why certain orbs have different colors (red, blue), and if there is a meaning to these colors. An orb is a solid or transparent "ball" of energy or light.
Some parapsychologists believe that orbs are spirits, or lingering energy from deceased entities. Orbs can appear in many different shapes and colors, with white orbs being the most common.
I have been capturing alot of orbs with my digital camera.
