The silvery wolf came over towards the fox, three times it's size but it studied the smaller canine with white eyes as Remus whispered, "have you ever used a Muggle or magical camera? Somehow, they managed to magic this to be able to not capture their photograph, but the very spirit of them. The problem is able to get them perfectly in frame as well as in focus - it's the only way to get this to work. It isn't perfect, but it's the first method we've ever had that successfully captures them instead of just driving them off."
