i wondered if there is, or ir's possible, to trigger image capture with brightness change..for example, i think that 'magic lantern' provides this, to capture lightning, or something like a car headlight coming into a scene... i would like to capture an oscilloscope 'sweep'; the phosphor has a bit of persistence, so it's not necessary to have μs tesponse time, may be useful to have even some settable delay?
