Here's the script I've been using to take long exposures all night long. http://chuckheron.pbwiki.com/TimeLapse Chuck's CHDK Timelapse vids I've used it on both my A560 and my S3 IS. They both seem to work pretty well. The set_prop to turn the display off doesn't do much on the A560. It blanks the screen on the S3 while it's taking the pic (that could just be what it does anyway) I'm using recent Allbest builds for this... Allbest quick reference Allbest firmware usage Script Code (save as "long-exp-clicker.bas" to your /CHDK/SCRIPTS/ folder) And here's a forum thread with settings for it.. [1]
