||Don't Kirlian auras change over time ?
||The stochastic corona discharge is always varying
anyway, even during the exposure. The conventional
(?) Kirlian photograph as we are familiar with it (if
you indeed ever were) is essentially a contact print.
In other words, its like when youre learning
photography in the darkroom and you place objects
onto the photographic paper and expose light to it.
Theres no focusing involved. Theres only recording
of the shadow falling onto the emulsion.
photography, theres no shadow or external light
source, but the object produces the light radiation
itself through corona discharge. The length of time of
a typical photo paper or film emulsion exposure
involves a summing effect of the moving around of
the corona discharge energy as light exposure. If it
moves from a specific area, it registers slightly less,
and if it moves back again it builds up the exposure
in that area. Youre seeing a summed aggregate
||Itd be like taking a photo of a candle flame,
except that instead of a brief exposure, imagine
youre shooting a ten second exposure to the flame.
Any flicker will cause it to register a feint image in
the moved position, but as it spends the majority of
time in the central flame position, that part will be
denser. If the flame is in a constant wind, the density
is spread around, looking like but not actually being
blurred (more statistically distributed (you could
think of it as being distributed across phase space))
and if therere no disturbance, the density is
gathered around where you see the flame, so itll be
||Same with Kirlian photos its a
long exposure that registers the statistic distribution
of stochastic corona discharge effects, and collapses
all that time continuity into one still frame.
||Similarly, a Kirlian photograph is an intersection of a
plane of imagery theres no focus or distance
differences. With holography you would record the
spatial differences, and as such, it would not be
merely a planar image, but rather, one with three
dimensional discrimination. It would still be
temporally-collapsed, though, but the resulting
texture complexity would be statistically
characteristic of the emitter used as a subject.
||sorry, I had a snowball in my ear; could you repeat that ?
||It can't work (first 4 and a half paragraphs).
||But it will work (last half paragraph).
||[IT] Do you actually have evidence that there is any
consistency of coronal discharge? Especially if something
like fingertip contact pressure (and thus contact area) is
||No, but with adequate funding
||Oh, and it doesnt really require contact, or at least,
not in the squashing sense as its a holograph of a
three dimensional object.
||My understanding was that Kirlian photography only worked
with contact, because it's the discharge of the electricity
from the object into the film that actually produces the
||Some fingerprinting kits were banned because they used dangerous forms of asbestos.
