Had torrential rain for about 25 minutes and a few rumbles of thunder... storm has intensified further but moved off now... There's constant rumbling coming from my north now (guess the storm is probably between Cheltenham and Tewkesbury somewhere)... unfortunately the "lightning picture" I'm still sorely after has escaped me again... had my finger on the 'fire' button, AF set, but my camera went into power save mode just as the lightning flashed! ... since then there's been no visible CG lightning although there's still constant loud thunder from the storm. Only wish this were a night storm... I'd lock the cam on a 8 second exposure and just keep taking pics for an hour or so hoping that I'd get a shot! Maybe my lightning shot just isn't meant to be... still, on the bright side, before the storm broke I got some nice convection pictures to go in my gallery later!
