Thanks Fred, Adam & Humayun
Fred - I'm not usually one for high-contrast, but the light was altogether weird last night as this came over. Contrast levels were naturally high - far more so than normal. I also boosted it a tiny tad in process too because I think it suits as well.
Humayun - you remember the last one that I took of the "twister" - Jan 26th, 2009. Yeah, it was pretty spectacular too!
