Hi Folks: As i have mentioned a couple times, I am heading to Airventure 2008. I've been there a couple times before, and every time, the pictures i get are less than satisfying. for example: http://www.flickr.com/photos/w8tah/2116414332/meta/in/set-72157603477159795 http://www.flickr.com/photos/w8tah/2115629665/in/set-72157603477159795/ http://www.flickr.com/photos/w8tah/2115618631/sizes/o/in/set-72157603477159795/ i know background is important and grey clouds do not help many of the areobatic aircraft are slightly blurred and the colors just dont pop out for high speed, shooting on a tripod is not realistic, but i can shoot at high ISOs for fast shutter speeds any and all suggestions/ cookbooks . etc are most welcome TIM -- Tim Holmes W8TAH - Amateur Extra Operator Medina County AEC Skywarn Advanced Storm Spotter Certified Certified Severe Weather Specialist StormNet Chase 9
