Hi Jeff,
Wow! Those are really some beautiful photos. They display quite a
variety of gas discharge phenomena not often seen by even seasoned
researchers. The length of some of the faint ghostlike
positive streamers is truly amazing, as is their failure to coalesce
into hotter leader discharges.
A few photos captured isolated streamers (called "space stems",
with diffuse discharges on each end) that characterize the propagation
of negative leaders. For example, multiple space stems can easily be
seen in the bright discharges on the left side:

Fainter, feathery and very detailed negative discharges are seldom seen
other than in direct discharges on photographic plates (such as in
Kinraide's work). And other photos capture heavily branched positive
streamers reaching to interact with diffuse negative discharges, such as
this magnificent shot. Streamers are poorly-conducting paths - the
consequence of air avalanche breakdown. In this photo, the high
resistance of the streamers (and lack of lower-resistance leader
channels), apparently prevents the connecting positive and negative
streamers from forming a low-resistance spark to bridge the gap:
For the first time color photos have been taken of Tesla's phantom
streams and Kinraide's various experiments. Hats off to Kelly
McJilton who manages to do what I tried unsuccessfully for 10 years.
Really great stuff. All photos are of corona from a 9" pancake coil
operating from a 3500V 8mA neon sign transformer. Clear positive and
negative phenomenas can be seen from the distinctly different fractal
patterns (forked branches vs feathery plumes).

they are magnificent.Jeff
