After the Storm

I went out after the storm last night to photograph lightning with Magic Lantern  firmware.  The firmware worked fine but predicting the direction of the strike was a problem.  Several times there were ground strikes outside the field of view which triggered the shutter but did not result in a dramatic image.  What did I learn in my first attempt?  Exposure for the ambient light gives the horizon some clarity.  I think the back side of the storm is safe with the lightning receding, this may be a false assumption.  The firmware works.

This was the western sky as the storm was clearing. Technical: Auto white balance was used to reproduce what I saw, the other choices did not seem real.
