Heck yeah! Cool stuff!
You can tell it's digital by the couple of maxxed out pixels in the shot. (it happens, no sweat).
The advantage is that you can actually take pictures of lightning, since if you miss a shot -- no sweat! you can delete it!
I got a Nikon Coolpix 995 a couple months ago, and blew about 70 shots on a thunderhead that set up 5 miles east of where I was at about sunset. No danger on this side, but underneath they were blowing the tornado sirens.
There was still plenty of light, so I didn't get the cool effects you got (nice job going for underexposure, btw), but here's probably the best of the ones I took. You can only see part of the lightning bolt in the picture.
(and yeah, I too had to knock down the resolution to get it to fit)
