You don't know what a photograph is? Man, you must have been living in some far off corner of the Earth Kingdom to have not heard them. They're one of the latest things!

Someone has this little box thing with a light on top. You stand there in a pose in front of the box, and the light flashes, and then a few days later, they can print what the box thing saw and put it on paper!

[Depending upon your point of view, Bolin is either the best person to ask about technology... or the worst.]
