That's right, one can say that this empty cameracase isa memento he left behind for me.
是的，这个照相机的空匣子，算是他所留给我的纪念品了。

When he first came, this was the very empty cameracase that he was carrying, slung diagonally across his shoulder just like how a traveler would carry his water bottle.
当他初来的时候，就带着这个，像一个旅行者佩着水壶般的斜挂在身旁。

I had my camera ready, just in case I saw something that would make a good picture.
