what I meant by jumping drifting trigger was the delay time the camera takes the picture after usb signal goes to zero.
Do you know what range the delay varied over, did you log that value ?
Used with a pair of cameras for stereo, we can get average delay-differences of about 100 to 200 microseconds.
If the Canon shooting-sequence could be interrupted even later in the shooting sequence, maybe 'less variable' delays could be obtained.
(it is just a point-and-shoot camera !).
If it was useful, your workshop could probably build a beamsplitter device that allowed you to capture the plasma in stereo.
