i never heard of orbs until i joined ats. i always thought those circles were dust on the lense. last nite i was at my sons christmas pagent and i
think i snapped one. i have more, sometimes they are in the pic and sometimes not. orb or not?
I looks like someone has the stained glass windows covered but opened a circular area for light to shine through.
that or perhaps they have a round lighted stained glass piece on the wall in the back.
from my very basic knowledge of quantum electrodynamics, light, when reflected, can reflect in patterns because at times, it cancels it self out.
that's what it looks like to me. like something is on the lens or something like that that gives the right type of distortion to make those
concentric shapes. i wouldn't imagine "orbs" would give those blank areas.
