Weather
Each of these photographs was taken outside of my house under different weather conditions. Each produced what appeared to be orbs or mists. None were paranormal. Each was a reflection of the light from the flash off of water droplets or snow in the air. I am confident that there are no ghosts in or around my house. We may get the occasional spirit passing through, just like anyone else.
The first photo shows my home during winter when the snow on the ground had partially melted. It was quite drippy outside. The orb in the photo is probably a water droplet off of the tree above my head.
The second photo shows the outside of my home during the winter when it was drizzling outside. You can see what appears to be hundreds of orbs. Obviously, taking photos in the rain negates the validity of anything in the photo that looks paranormal.
The third photo shows the field across the street from my house during a snowstorm. It looks like there are dozens of small, bright orbs in the photo. They are more intense than in the photo with rain, but snow gives a more solid reflective surface.
The fourth photo shows the field across from my house during snow and high winds, resulting in blowing snow. It looks like dozens of orbs and a misty form. Both are caused by the snow in the air.
This last photo shows the front of my house in the winter during a fog. It looks like a very eerie misty form has taken up residence.
The lesson to be learned from these photos is that you must pay attention to the weather when doing a paranormal investigation. High humidity, rain, snow, fog, dew on the ground or anything that puts a lot of water in the air or on the ground as a reflective surface can result in photos that could be misinterpreted. When I am evaluating a photo, I am more likely to assess it as paranormal if it has a single orb, especially a dense one, during warm weather. It is highly unlikely that we will find snow in June or one single rain drop.
