Both pictures taken with a S2 IS, CHDK loaded.

Lightning

This picture was taken at night with 15" exposure and F/4.5 aperture. As you can see the picture too soft and too bright. I think a 10" exposure and maybe F/6.3 aperture would be better. To shoot clash I use a homemade script which is an intervalometer working only over 1". All sleeps time are defined in the script for all exposures between 1" and 15". I need to work again for better shoots. I'd like to see yours. This kind of shoot is typically a good way of working with scripts. A piece of luck is welcome.

With the same script I did this shoot. The image is sharper because I used a faster exposure (8 seconds) and a smaller aperture with 6.3. I think the result is better but it's not enough. I followed advice from the Dpreview forum. Good advice, thanks.

Ligntning Photography done automatically with MX3's Motion Detection!

Taken with MX3's Motion Detection to trigger automatic shooting with lightning detection using a simple script. All lightning strikes are preceded by a leader-strike, the main strike(s) happening anywhere from 100-300 milliseconds after this leader-strike. MX3's motion-detection routine has a 10ms response time! While browsing the main CHDK Russian forums, I ran across these. Vitaly and others tested MX3's implementation of motion detection to see if it really was fast enough to capture lightning strikes. IT IS! [1] [2] [3]

And more -- [4] The 1st collection done with the usual manual method, tripping the shutter and waiting and hoping. The 2nd and 3rd collections were done automatically with a motion-detection script.

Now you can just set up the camera, run a simple motion detection script, then head back into the safety of shelter. Every one of your frames should have a lightning strike on it. No more risking your life while hoping that you might get one while keeping the shutter open! MX3, you may have just saved some lives (like mine)! :-) --GrAnd 14:12, 14 October 2007 (UTC)
