Actually, weird as it seems, that wasn't my finger over the lens...the sky looked like that all by itself. Never touched the picture in PSP or Photoshop.
OF course its VERY dramatic! great capture of impending storm...wonder what it was like after the storm hit! Would have been a great shot to have the aftermath to that one.
haha i looked at this for the longest time and i was like "what finger, i dont see a finger!". It looks like a perfectly good sky to me, with a storm forming, I think it's a good pic
