I was sitting inside working in my office yesterday when Kylie strolled in from walking the dog with the neighbors and casually said, "Storm's roling in... you're missing the clouds.  There's good light out there, but you better hurry; it's starting to sprinkle."  In about 11 seconds, before my chair stopped completely spinning, I was outside with camera in hand.  You've heard of storm chasers?  I was light chasing. She was right.  There was good light out there.  And those clouds were ridiculous.  I took a couple images before the weather completely turned, and here's 2 of my favorites.  These are HDR (High Dynamic Range) images, and you can see a tutorial I posted about how I create them here.
