Actually I was just trying out my new (second hand) lens and happened to notice this unsuspecting passenger's interesting reflection under the light conditions. But since you put the concept so nicely, I'll take it! :bsmilie:
Some more it was a KM 5D with that loud mirror slap! But I was 3 seats back so maybe he think I was shooting some one/thing else
Thanks all for your comments! They've helped me to come upwith a more suitable title.
