So you've arrived in Japan and have just received your new iPhone. Everything is going well, the menu is in English and the service seems to work without a hitch. Then you go to take a photo of your sleeping baby and "snap!" the camera makes a loud shutter sound. Loud enough to wake baby. Searching for the Settings option to switch off the noise, you come up empty handed.
There's a reason for this. In Japan, digital cameras and camera phones must make an audible noise when a photo is taken to allow people to know they're in a picture. And when you read about some of the pictures people try to take on the train, it kind of becomes obvious why. When baby is asleep, best leave them to sleep in peace.
