Hi all, I wondered if you guys could help me with this question. I have been showed a picture of a lightning. It is not the complete lightning on that picture, maybe 1-2 thirds of it. To me it looked a little blurry, so I asked if the photographer had used a tripod to make sure the camera was completely stable for the time the shutter was open. (30 seconds) He said that he did use a tripod, and that the blur I was seeing was really caused by multiple flashes taking the same path. Looking at the pic closely you see indeed several images of a lightning on the exact same path, but moved a tiny little bit side wards, maybe the fraction of a millimetre. So my question is, is this possible? After thinking about it, it does seem to me that multiple flashes of lightning originating and ending in the same (or almost the same) spots would still take a slightly different path every time, and that it is more likely that something moved the camera a tiny little bit just when that lightning occurred. But would the lightning be "slow" enough to cause such an effect in that case? What do you all think?
