before the lighting .
So this means the camera will sit quietly, for many many minutes, waiting for a lightning strike? And immediately before the actual strike occurs, it takes the picture, missing the actual shot by less than a second or so?
Tried just about evey value.
If you turn the sensitivity value up ( i.e. try every value ) then at some point the camera will not react to anything - and you typically do not have to go very high.
Unless you are adjusting the wrong value. What is the exact text of the parameter you are adjusting?
