Thanks Lesley. Miss Sarah Dipperty helped me again.Wow! Simply awesome!!
Thanks Rob. "Sometimes" is exactly right. (Fortunately, with my two, I can say "most of the time."Brilliant, brilliant, brilliant! Aren't teenagers great?! Sometimes
) Thanks again.
The double-exposure? Wish I knew how! My guess is that my shutter fired (I wasn't using flash) and the other person's shutter fired--with flash--a particle of a nanosecond apart in time. This, I'm guessing, caused my shutter to freeze the subject on the other person's red-eye reduction light, and again on the flash. Whereas without the flash I would have captured significant blur. Does that explanation make any sense? Thanks Chris.
Bet you I could! (If given several million more tries under the same circumstances!What a cool effect - bet you could't do that a second time!
Must be all that practice catching celestial fireballs - ninja reaction times.
) I'm hoping Pete or Hamish or someone else will pop in and give an opinion on what might have caused the effect. Celestial fireballs...? I admit I am rather adept at capturing such phenomena. Yes,...you may be right, Chris. 
Yes exectly, Pete. It was Miss Sarah's flash that did it. (By the way, I have subsequently discovered another picture, somewhat similar, that Miss Sarah had a hand in. Perhaps I can post that one tomorrow.) The observer is my daughter, Meg. Anyway, thanks very much, Pete.Was that Sarah's flash by any chance Brian. It certainly has that look about it!! Fabulous place of legs and circle and the observer adds so much. I like this a lot!
