Here is an interesting orb pic I took (below). I still think its probable that most of my orb pics are just lens flare or dust, but this one got me wondering. Notice how the picture frame covers part of the orb, and the orb is behind the picture frame. That shows it has dimension and depth at least, not a super-imposed image. I keep seeing this big orb always hanging out with the smaller orb in a lot of my pics, which is kind of cute.
