Sirius Black had a camera.

It was an old-fashioned, muggle camera that he had bought during a stay with the Potters in the summer between his third and fourth years at Hogwarts, prompted by a conversation with Mrs Potter.

He'd presented it to the other Marauders on their first night back in their fourth year.

"This," He had proclaimed solemnly. "Is our camera. With it we shall document everything we do and collect many embarrassing photos that can be used on our 17th birthdays to cause mortification and general mental scarring."

This, of course, meant that James was forced to explain to Peter and Remus that his mother had shown Sirius all James' baby pictures and told him how it was traditional to show embarrassing pictures of a person on the birthday they became an adult. Sirius had thought this was a wonderful idea – his family did not approve of photography for fun – but only because he liked the idea of sharing amusing pictures of himself, putting himself in a minority of roughly one in the whole country.

He kept all the photos in an unorganised mess in an album that he carried with him wherever he could.

Beside each picture was a date and a few words hinting at the story behind it.

It was a given that he wanted these stories to be told.
