   My framing for the Two Camera Timelapses of Tornadogenesis!

The light blue larger frame illistrates the "Wide Angle" view of the updraft in the Timelapse below. While the brighter smaller frame is that for the "Closeup" shot with the JVC on DashCam III further down.


   Timelapse with Wide Angle View!
   Location: Ford/Clark line, 2 mi W of Ks34
   Time: 200X : That's fast! 1 second equals 3 min 20 sec in realtime!

   Closeup (zoomed in) Timelapse with JVC on DashCam III

The picture is actually from a 6x7cm negative. But the framing is close to that of the video timelapse, and makes good eye candy! :-)
   Time: 60X : That's 1 second seen equals 1 minute in realtime!

I shot a TL from 30 mi away in steady 25 mph ambient surface winds. So I ducked under the beast to find a 20-30 mile long linear RFB, Rain Free Base. I saw signs of it wanting to buckle, so I set up the timelapse and let it roll. It builds into a wall cloud with a "flying saucer" structure, not seen cause even the Wide Angle adapter on the GL-1 is not enough. Then the updraft tightens and rotation sets in. Followed quickly by an RFD cutting off part of the updraft and resulting in a tornado. Watch for the RFD cut, and "pulses" of the RFD. Are these pulses, real pulses, or are they just precipitation laden areas of the RFD, and since allowing the RFD to become "visible", gives the appearences of pulses.
