Are all the MD_lightning scripts gone? I wanted to try it out, but the only one i could find was the one on the wiki and that one doesn't seem to like to work in low light conditions for me and my s3is.
Barney deleted all his posts so the scripts aren't here anymore. You may be able to find them somewhere, but I'd recommend trying mine instead. The lightning detection speed (in fast react mode with default settings) should be pretty much equal to Barney's scripts since my MD loop is sufficiently similar to his as far as I can recall (both come from the same thread where the speed was improved by various people, Barney's scripts playing a central role).
Find my script in this thread:
Fast MD with burst/preview modeNote that nobody has tested those two latest ones yet (the ones for cameras with a separate video button), so if they fail, use the generic Digic II one... it should work if you only shoot stills or bursts of stills.
As for low light, this is a known weakness of the entire MD feature. In low light, there is a lot of noise in the viewfinder image, and you need to increase the threshold setting to stop MD from triggering from noise. Increasing the threshold also means that the darker it gets, the more prominent the motion must be (in terms of luminance, if you are monitoring the luminance channel) for motion to be detected reliably.
For more information, read the documentation to my script, it may help you to better understand the limitations and all the parameters no matter which script you end up using.
