Here are a number of example photographs taken in a variety of weather conditions. Which show evidently how natural conditions coupled with the camera flash create on screen anomalies which have sparked the "spirit orb" conversations.
Orbs are created as a digital camera artifact, with the flash being so close to the lens anything in and around the lens becomes illuminated creating light balls, strange reflections, coloured lights - the multiple colours are generated much in the way a rainbow is created. And is a brilliant example of this, light is made up of different wavelengths each a different colour of the spectrum. As light is scattered through a droplet or moisture it splits into its colours.
A particularly heavy downpour in Autumn 2007, see how the light captures the raindrops thought to be the "teardrop" but are in fact spheres/globules
Same rain storm
Moisture and water kicking out droplets caught here as "Orbs"
The act of waving incense photo captures wave of the smoke being generated.
Paranormal Network took this image a Mind, body and spirit festival a number of "psychics" and those with connections to information none of us living folks here, apparently a whole communication network of truth - they revealed this image to be that of a actor who had played Phantom of the opera, which is why there is the "theatre" mask. Another said great sadness as it is the lingering spirit of as girl who is on the verge of becoming an angel due to her pure nature. A third said angry and vengeful spirit who was following me and that i needed a clearing and a healing which would cost me just 25pounds. What this was really was a "sage jostick" being waved in woodland.
A trip to Matlock, looking under the bridge with the water flowing beneath and damp moist conditions seemed a great photos and low and behold "orbs".
A misty with no flash
A misty with flash. Now we have mass amounts of "Orbs"
