A problem with KAP panoramas is the variation in camera position during the capture sequence . In an effort to reduce the ammount of camera movement the kite flier has 4 options:
- Wait for a more stable airflow (may never happen but its surprising how time of day and season can change the motion of air from a particular direction.
- Speed up the camera movements so that the motion between shots is as little as possible.
- Get a ‘360’ lens
- Use a panoramic camera
I’m investigating option 2 as click-Pan Pro can be set to run pretty fast, it even has a continous pan setting (which I have not dared to try yet!)
The ‘C’ path with the tilt servo removed gives 2 shots per pan move, this ( Leica DLux 4/ Panasonic Lumix LX3) camera can’t keep up with the shot rate and saves one (Autofocused and stabilised) shot per step. The shutter servo takes a pasting too!
For panoramic cover I use the portrait aspect and a fixed tilt to try and keep things simple at the stitching end.
and the wobbling height problem is revealed. This one is with the rig balsting away at a 2s interval. The camera uses image stabilistion so the AF hit rate is good but, oh boy, what a mess of the horizon line!
Fortunately the pan is taking 20 shots to the circle giving a generous overlap so maybe I can take out a few and see if the result improves:
The options with clickPan pro now look like this:
Most of the paths have quite a long gap from horizon shot to horizon shot, path E should give the best panoramic cover but I think the ‘ high speed’ option of working without the tilt optimises exposure variation and camera movement. I shall experiment with the pan step, as I think I’m using too big an overlap, so I’ll need to keep the switch settings handy.
