This post is dedicated to all of us who may have hinted at our lack of confidence or not measuring up in experience or gear to get "the shot" we're looking for. Well to all of those folks (myself included some times) let me say this... sometimes you just throw caution to the wind, fool around and see what happens. Digital film is free, who cares.
I was at my nieces high school graduation a week ago and when it was all over I held up my K-x (like the crazy people do at the end of a football game when everyone's crowding onto the field) and I got this. Let me tell you why this is such a great and very lucky shot. I wasn't even trying for a reflection pic, I was just going to take a picture of my son and didn't care what I got. Really I was just fooling around. I took it into my son's face and in his glasses you can see everyone who was there to see the graduation.. me, my parents, my bro-in-law and his mom, my sister and the Graduate (in the white framed sunglasses).
So just go for it... worked for me.
(BTW, did only very light adjustments in post with LR4: exposure, sharpening and cropped his mouth out.)
