You can also collect evidence of ghost through the use of cameras. Digital or film cameras work fine. While pictures can say a lot unfortunatly they can also tell half truths. The most controversal piece of photo evidence is orbs. Orbs are described as balls of energy from an unknown source. It is said that a ghost collects energy around it to try to manifiest and that enegery comes out as a round shape on film.
Unfortuantely there are a lot of other things that can look like an orb. Dust, pollen, insects, moisture and in some areas sand can all look like orbs. And digital cameras can also create false orbs as well. These are spots in the picture where the pixels don't fill in the area completely. They look perfectly round. Reflections of the cameras flash, ghost hunters flashlights and other light sources can also cause false orbs. Most false orbs are usually pale white or blue and are transparent.
True orbs tend to be bright and solid. In some cases they can be caught in motion with wavey (or rippling) tails. The tails can also be straight too.
See the multiple orb coming through the doorway. They have each have a different light intensity to them. But they are all pale and translucent.
The orb on one of our members belly is also pretty pale and see through.
The first orb has an interesting bit of info with it. At the time it was taken two of our group members felt an angy spirit was following us, as if it wanted us out of the area. As we went through to get out I kept taking multipule shots and this same colored orb was seen in all the shots, in different spots of the shot. Once we got out of this stretch of woods I took another shot and the orb was see just at the border of the woods. It had stopped following us. Mind you we could not see it with our own eyes but the camera caught it. The second shot was later the same night when we felt the entity had gone. This site contained mulitple spirits and we had many different encounters there. You can go to evidence 2 to see more on this particler hunt at Highland park in Rochester, NY.
