UBASIC/Scripts: Lightning script -- Fudgey
Written for/on: Powershot S5 IS
Also works on: A540, A550, A590 so far.
Doesn't work on: A720 IS and some others.
This is basically a very fast and responsive motion detection script. This will definitely solve your
problems if you want to catch lightning, (thus the title) or anything fast, however some objects will blur
when the light conditions are insufficient. Enjoy this script!
