this is a test with my updated sunset script. obviously the settings need to be tweaked but the night pictures are beautiful.

sorry, my project has taken on the name "robot camera" because i need a way to talk about it with my friends. no, there are no upright and walking robots taking pics like japanese tourists but just a camera that can adjust its exposure and continue taking pics pretty much forever.

this is the first satisfying results. still needs more work but the end is in sight. (it hasn't always been)

the video shows the exposure setting working well until morning. i think i can fix that by reading up on the sunsetF14 script and understanding the settings better.

the bottom image is from midnight in so little light that you'd see almost nothing. its a 15 second exposure at 400 ISO. I would prefer a 60s image at 100 ISO.

the script ran for nearly 24 hours to create the movie at top. it has not crashed since i switched to shoot() from press("shoot_full")

I'm interested time-lapse shooting session that make your script. I think that is mutch better than other scripts. Or you asking something else? (i'm not so good with english, sorry)))
PS the only shortcoming (excluding errors on sun shining scenes) is that day/night/morning/evening looks almost same. Can you force script to make photos more dark after 20:00-21:00 (using camera clock)?

there's a lot of documentation and posts about these scripts:  http://chdk.setepontos.com/index.php/topic,2156.0.html  You can set parameters as you want...for the night, dusk and day...it's amazing but not really easy...lots of tests to do
I have some trouble with it for the moment (press shutter to close...)...it crashes at moments...and i don't know codes...
good luck

my script doesn't use the parameters. while people like to see night pictures looking like night, its a technically incorrect way to take a photo. further, its extremely difficult to program a camera to take night pics accurately. my script makes the best exposure possible (most detail) and its up to the photographer to darken them later.

mattkime,

I didn't read your script but autoexposure with intervalometer is very simple to get, day and/or night.

Continue to search and work, you will find :) at your experience
