However, it seems like the camera needs to focus before responding to motion. I hope someone has been successful with the A2000 because this is one of the main reasons I bought it!
If you use the "Fast md" setting of the script, the camera will focus only at the start.

Which brings me to another question: is there an aperture setting for the A2000?
No, the A2000 and other newer A series cams do not have adjustable aperture. The A590 was the last AFAIK. You can tell which cameras have an adjustable aperture by checking in the canon specs whether they have an Av mode.

-Why put the camera in record mode (i'm assuming this is the video record mode)? I've tried it but it simply takes small video clips of nothing.
No, in canon terminology, "record" mode is any shooting mode (still or video), as opposed to playback mode.
Don't forget what the H stands for.

I am sorry if this has already been answered somewhere.  I just could not find it.  Will this script run on my A700?  I am running the Allbest CHDK now.  Thanks.

Hey guys.
Been using CHDK on my new s90 for a while now, and of course I love it. THANKS!
Now I've put this script on and it seems to be working fine. However, tomorrow there will be a thunderstorm in my area (the first since I've loaded this script) and I'm just wanting to make sure that I have everything ready to shoot some lightning!

So my question. What should I set the threshold, pixel step, collumns....ETC, to? I've search far an wide on this forum and this thread, and maybe I've missed it. Do you guys have some settings that are tried and true for shooting lightning?

I don't personally know of any tried & true settings. I got some of my best pictures of night lightning using the script defaults. After that I started experimenting with the settings based on the storms characteristics & distance away. For example when the storm is fairly far away and/or not very bright I may try lowering the threshold. Sometimes I set a longer exposure.

In case you didn't see it here's a good explanation of the various settings http://chdk.setepontos.com/index.php/topic,471.msg9169.html#msg9169

I haven't had much luck in capturing a good shot of daytime lightning. But I only got my camera & started using the script last year. This year we're having a drought where I live, so not having to many thunderstorms. The few I've had were short-lived, to unpredictable or just fizzled out.

I'd suggest starting with the defaults & then experiment from there. Good luck!

Ixus 860 here, with MDFB-080914.bas.
It says, sometimes:
uBASIC: 90 Unk Key
uBASIC: 91 Unk Key

So what is wrong and why can't I get it to shoot?

Check to insure you are usng the correct version for your camera. From the script documentation...

"Note: There are two versions of the script, for
- cameras with no video (movie) button (A, G and IXUS/SD series)
- cameras with with video (movie) button (s2is, s3is, s5is, tx1)

S series and TX1 handle video mode differently from the A, G and IXUS/SD series cameras which is why they need their own version."

Hope this helps.

In the zip is also a MDFB-080914-VideoButtonModels.bas which I did not use.

I did use MDFB-080914.bas for models which no video button according to your small list.
So was I right by using the version stated?

This is using chdk from ixus860_sd870-100c-0.9.9-1038-full.zip.

It seems you used the correct version for your IXUS. Since I can only test using a SX20, I can't offer any more guidance. Hopefully another IXUS user can help you out from here. Best of luck!

OK, thanks. Maybe this some sort of bug? (undocumented 'feature')
