Can Spell Competition in Ottawa, 2006. This photo had more colourful orbs than I was used to seeing. Also- There's an odd pattern inside the greenish orb that matches the blouse of the woman beneath it.

 

I've given up trying to count the number of orbs in this photo, which was taken at a local 'Haunted Farm' attraction. People were waiting for their turn to ride the haunted hay ride, watching the jugglers. (This is not the photo I have with the most orbs, that distinction goes to a photo taken at a cub scout meeting with too many identifiable children's faces to post in a public place.)

 

   I don't know what orbs are, whether they're spirits from a higher dimension,visitors from other dimensions, or phenomena with any of a dozen other explanations. I have been assured that they are not dust, imperfections in a camera lens or moisture in the atmosphere. (The explanation? Whack a pillow or other dusty object and take a photo, take several photos, none of the dust specks look like orbs, do they? Squirt a water bottle with a mist setting and take several photos of that- from various angles, into the sun, away from the sun, parallel to the sun... What you get will not look like orbs, either, but don't take my word for it. Test reality-)
