Summary: What we know about
the 'Orb Zone'
Here is a reminder of our
'Orb Zone' diagram:
The Orb Zone is the area in
front of the camera where dust is photographed as orbs.
The following factors define
the size of the Orb Zone:
- Being in front of the near
point of visibility - between here and the lens orbs are
out-of-focus but so big that they appear invisible.
- Being in behind the near
point of focus - any particles further away the
will be in focus and too small to see. Behind this
line the particles are out of focus and potentially
visible as orbs.
- If the particles in this
area are close to the flash (or, rarely, another light
source) they will be illuminated as orbs.
We have also established
that there are no dust free locations and that simply
moving around causes dust particles to become airborne.
This concludes the basic
explanation of orbs. The
explanation
page carries more technical information and the
answers
page carries more generic questions about orbs.
The
answers page is particularly designed for
those who think most orbs are normal, but that some
break the rule.
