This photo was taken at at Mokuleia beach camping grounds on oahu,Hawaii. i went on a camping trip with a bunch of friends. it was taken April 24 2010. i didnt notice the "smoky" apparation above our heads until the other day when a friend pointed it out to me. i have a digital Sony cybershot 7.2 mega pixel camera. no other pictures that i have ever taken on this camera have anything like this on them. and i dont smoke cigarettes and neither do my friends so i know thats not smoke. what is it?
