Wife: "Is that Adolf Hitler through a prism?"

Me: "No, it's a reflection in a train window that I've been playing around with."

Wife: "I like it."

Over to you ;-)

To which I could add: telephoto zooms are not especially useful for train window reflection shots as you end up with a totally unrecognisable background. In future I'll probably stick to my 17-40 for this type of image.
