Regarding the best orb pictures I have ever seen. Consider that it would be interesting to see 3D
stereograms of Borley Church orbs. A distinct, 3D
field of orbs would address the question of whether
this effect is being caused by moisture in the air
and/or water droplets on the lens or by something
else.
Also, I am intrigued that many orbs have distinct
tails below the sphere which suggest that the orbs
are traveling up. Given the camera strobe should
freeze motion I have no ready explanation for this
effect. Indeed, if I remember correctly, a strobe
provides an effective shutter speed of 1/10,000 second
under black conditions as these pictures where
obviously shot. (Note that strobe photography can
freeze a moving bullet. In fact, shutter speeds of
1/2000 can freeze object motion in daylight.) So
either I'm remembering strobe speeds wrong or those
"water droplets" are traveling quite fast!
Regarding the orbs with a tail, many tails taper to a
width smaller than sphere part of the orb. If this
tail was primarily an effect of the strobe on a
moving orb then the entire length of the tail would
have to have the same width as the orb. This is
because the tail would be a constant width blur of the
moving sphere. This is not to say that no part of the
tail isn't a blur of a fast moving orb. However,
interpreting any motion with respect to the appearance
of an orb is more complicated than I initially
thought.
