Photograph, Photo
You put your fingers and an ear on a stool in the sun so you can get your photograph taken. This is a glamour photo, so you have to be in one of these weird, cheesy poses for it to come out jusssst right.
Imagine putting your fingers and your ear on a stool, now try to relax your head a little bit, and smile for the camera. This is a professional photograph, so you better do what you're told!

As you're getting the photograph taken, the photographer tells you to say Satsuki (さつ). He says it's like saying cheese but more effective. Satsuki!
Go ahead and say Satsuki out loud, all happy-like. Makes a pretty big smile, right? From now on you should always say Satsuki when you're being photographed.
