5D Mark ii & 550D

Captured using ML's Motion Detect exposure setting - value of 6 during the day.

Iso 200, f/5.6 , 1/80 second

I've been able to capture lightning reliably during the day using ML using both exposure and frame difference.

The above was taken using exposure difference with a setting of 6

The above was using frame difference.

Its trial and error, try setting up inside by pointing at your TV in the daylight - this is a good test for exposure ..

Good luck

I use ML to do timelapse videos, checkout one here and others on my Vimeo feed

My workflow is:

Camera set to Manual -
RAW only - no JPG
Auto WB
Iso either 1600, 3200 or 6400
To avoid star trails and not overexpose, for a 16mm lens - Exposure - 30 sec (iso1600), 20 sec (iso3200) or 15sec(Iso 6400)
For other focal lengths, to avoid star trails use the formula  Max exposure= (600 seconds / (focal length (mm) * crop factor).
Aperture - widest - I use f/2.8
Set to not preview image after taking a shot
Set focus to infinity and lens to relevant zoom

Set ML to turn off display, and redraw after 30 secs
Set Timelapse for interval of two seconds for an unlimited number and to start without any delay

To avoid fog build up on lens, use the small packets of hand warmers you can buy - just attach one to your lens with an elastic band http://www.xtm.com.au/products/accessories_hand-toe-warmers.html

I then develop with Lightroom and create the timelapse movie from the "Slideshow" workflow in Lightroom using some free timelapse presets downloaded from here http://lrtimelapse.com/download/

Easy !!! Good luck!
