Orbs are controversial in that many, if not most, can be attributed to dust or other aerial contaminants, or reflections, but some just can't be explained. My orb photos could probably fit into any of those categories. Here they're presented unedited save for one (the Native American tipi, gently lightened to show that the orb is in front of the trees and is not a full moon), and whenever possible, the circumstances are also presented. Many of the timestamps are incorrect, so I'll also try to give an approximate timeframe for each. Enjoy!
Summer 2008. Look at the far wall above the framed certificate.
Date unknown. The fan was not on at the time of this shot. The orbs could be reflections from the light covers, but I don't know
This orb appeared during Jen's second studio shoot (on her upper thigh).
The sun was behind me, and it's clear the orb is in front of the trees.
I have no answer for this. Jen was meticulous about dusting (before Connor became a toddler), so this probably isn't dust.
