I took most of my bracketed HDR photos in sets of three: one exposed normally
(typically the way the camera wanted to expose it), one underexposed by -2EV,
and one overexposed by +2EV. Then I'd combine two or more of them using the
HDR program to get a full-range output.
This photo is actually the -2EV from this trio, which I like because it captures
the most dramatic view of the clouds.
